Volume 5, Chapter 1 is the first useful checkpoint for what Maomao learns through the locust and famine-risk material. It gives her a practical way to distinguish observation from rumor and turns Shisui's presence into a source of questions rather than simple trust.
Continue through Volume 5, Chapters 13-16 for the Western Capital revelations and their emotional consequences. Maomao gains information, but she also gains a sharper understanding of concealment, chosen identities, and the cost of surviving inside a factional crisis.
Continue with the locust comparison and the Shisui secrets guide for the surrounding evidence trail.

The short answer is that Maomao gains four things from Shisui: a rare kind of casual friendship, a sharper understanding of disguise, a material trail of knowledge that keeps speaking after Shisui is gone, and a new way to read threats that are bigger than one palace mystery.
That last part is easy to miss. In Light Novel 5, Shisui's presence returns through drawings, field guides, insect observation, and the question of who was trying to preserve certain knowledge. She is absent from the room, but not absent from the mystery. More importantly, her insect knowledge points toward a danger that is not romantic, decorative, or symbolic: a locust disaster capable of damaging harvests and shaking the country.
For the identity side of the reveal, start with the guide to Shisui's secrets in The Apothecary Diaries. This article focuses more narrowly on what Maomao receives from knowing her.
Why This Question Matters
Maomao is not the kind of protagonist who announces her emotional growth. She notices. She files things away. She converts discomfort into analysis. Because of that, it is easy to miss when someone actually changes her.
Shisui changes her in a quiet way. She is not a mentor, rival, love interest, or obvious moral teacher. She enters Maomao's life as someone odd enough to feel harmless: a girl with insects, strange interests, and an easy rhythm that does not demand proper court behavior.
That matters because Maomao usually protects herself with distance. She can work with people, help people, and even risk herself for people, but she rarely lets a connection become simple. Shisui gives her one of the few relationships in the rear palace that feels loose, funny, and unforced.
Then the story reveals that this looseness was never simple. That is where the real gain begins.
Shisui First Gives Maomao Friendship Without Demand
The first thing Maomao gains from Shisui is not information. It is a space where she does not have to perform the version of herself that the court expects.
With Jinshi, Maomao is always negotiating rank, attention, pressure, and the danger of being noticed. With higher-ranking women, she must calculate manners and consequences. With doctors and officials, she has to prove usefulness without becoming too visible. Shisui is different.
Shisui's oddness gives Maomao permission to be odd too. Bugs, herbs, strange observations, and casual conversation make their bond feel almost outside the palace's usual performance. That does not mean Shisui is innocent. It means the friendship gives Maomao a brief taste of ordinary companionship in a place designed to make ordinary companionship difficult.
For a character like Maomao, that is not small. It is one of the few gifts she does not know how to name while she has it.
What Maomao Actually Gains from Shisui
The answer works on several levels. On the surface, Maomao gains a friend who makes the rear palace feel less airless. Under that, she gains a new way to read people who hide behind roles. Shisui is not only Shisui, not only Loulan, and not only a cheerful insect lover. She is a reminder that identity in the court can be layered, performed, protected, and weaponized.
But the most important gain is practical. Shisui leaves Maomao with a trail of observation: insects, drawings, field guides, records, and the habit of looking closely at what powerful people ignore. Maomao already understands poison and medicine. Shisui expands that attention outward into ecology, agriculture, and the fragile systems that keep a country alive.
That is why this relationship matters beyond sadness. If Shisui only gave Maomao emotional pain, the arc would end as tragedy. Instead, Shisui gives her a method. A tiny insect can become evidence. A copied illustration can become a warning. A hobby dismissed by officials can become the first sign of a crisis moving through farms and storehouses.
In that sense, Maomao gains a harsher kind of maturity. She learns that affection and investigation do not always separate cleanly. The person she misses is also the person whose traces may help her understand a threat large enough to reach the food supply of Li itself.
The Thing Shisui Leaves Behind Is Not Just a Memory
Once Shisui is understood through Loulan, the earlier friendship becomes more complicated. The reveal does not erase the warmth. It makes the warmth harder to categorize.
But Light Novel 5 adds a second layer: Shisui also leaves Maomao something practical. The insect drawings and field-guide trail make her absence feel almost investigative. Maomao is no longer only remembering a strange girl who liked bugs. She is handling the residue of that girl's interests, habits, and unfinished knowledge.
That is the part the article has to center. Shisui's gift is not a keepsake in the sentimental sense. It is closer to a delayed clue. Her love of insects becomes a language Maomao can still read after the Shi clan incident has already changed everything.
This is why the question "what did Maomao gain from Shisui?" cannot be answered with friendship alone. Maomao gains an object lesson in how a person's obsession can outlive their public identity.
Why the Insect Guide Matters in Light Novel 5
The insect guide matters because it turns Shisui's "quirky" interest into evidence. Earlier, bugs could feel like personality color: Shisui likes insects, Maomao notices, the reader remembers. Later, that same detail becomes structurally important.
When Maomao encounters the guides and the missing or recovered volumes, the story is telling us that Shisui's knowledge was never decorative. Bird, fish, insect, and plant records are not just books. They are a map of who observed the world carefully enough to preserve what others ignored.
The insect material also links back to one of Maomao's strongest traits: she trusts concrete traces more than official explanations. A court rumor can be distorted. A family name can be disguised. But a carefully observed insect, a copied drawing, or a strange gap in a field guide gives Maomao something firmer to follow.
That lesson connects to the wider court structure. The article on The Apothecary Diaries Light Novel 5 looks at how the story expands beyond individual mysteries into political pressure. Shisui's leftover clues prepare Maomao for exactly that wider, harsher reading of people and evidence.
The Locust Threat Raises the Stakes from Personal Loss to National Survival
This is the part that makes Shisui's gift much larger than a sad friendship souvenir. In Light Novel 5, the warning is not a vague pest problem. The text points to locusts: insects that can move from edible field nuisance to crop-destroying national disaster when their numbers explode.
That is why the insect guide matters politically. A locust outbreak does not stay in the fields. Failed harvests mean hunger. Hunger means unrest. Unrest weakens border defense, court legitimacy, tax stability, military provisioning, and the fragile trust between provinces and the central government. In that sense, the locust threat can become a threat to Li's survival.
Maomao gains the ability to see that scale because Shisui taught her to take insects seriously. What looked like a harmless obsession becomes training in ecological attention. Shisui leaves behind a habit of looking downward: at eggs, wings, leaves, soil, eaten stems, small changes that nobles would never notice until the consequences reached the capital.
This also deepens Maomao's growth. She has always been good at poisons, bodies, symptoms, and hidden motives. Through Shisui's leftover insect trail, she is pushed toward a wider diagnostic field. The "patient" is no longer only a person. It can be a crop system, a province, or a country that does not yet understand it is sick.
That is why Shisui's legacy hurts and matters at the same time. Maomao loses easy access to the person, but she keeps the method: observe what others dismiss, connect small traces before they become catastrophe, and never assume that something tiny is harmless just because powerful people are not looking at it.
The Suirei Connection Makes Shisui's Gift Bigger
Shisui's legacy does not stop with Maomao feeling sad. It points outward, toward Suirei and the people who remain after the Loulan/Shisui reveal.
That is why the later Suirei material matters. When Maomao follows the trail of records, insects, plants, and medicinal knowledge, the story is showing a chain of survival. Shisui may be gone from Maomao's daily life, but the knowledge around her has not vanished. It has moved into books, copied sketches, half-hidden connections, and people who still carry pieces of the same past.
Suirei also makes the insect problem feel less like one girl's private hobby and more like a preserved network of practical knowledge. Plants, medicine, insects, and field records sit beside each other because survival depends on reading them together. A country does not fall only from poison in a cup. It can also fall from ignored locusts in the grain fields.
This gives Maomao something deeper than closure. Closure would make Shisui easy to file away. Instead, Maomao gains an unfinished inheritance: a reason to keep asking what Shisui saw, what she preserved, and who else was connected to that knowledge.
This is why fans keep asking whether Shisui will return. The question is not only about plot. It is about whether this trail will ever lead back to the person who made it feel alive. The separate analysis of whether Shisui comes back in The Apothecary Diaries exists because her disappearance leaves a gap the story does not fully close.
How This Connects to Jinshi and the Court
Shisui and Jinshi teach Maomao different lessons. Jinshi forces Maomao to face power that keeps reaching toward her. Shisui forces Maomao to face a quieter problem: evidence can survive even when the person who created it is unreachable.
That contrast helps explain why Shisui matters to Maomao's larger arc. Jinshi makes Maomao negotiate attention, status, and unwanted proximity. Shisui makes her confront the limits and power of observation. Maomao can notice many things, but Light Novel 5 shows that she also has to notice what someone left behind for later.
If you are tracing Maomao's relationship with power and trust from the Jinshi side, read Understanding Jinshi and Maomao Dynamics. Shisui is the quieter mirror: less romantic tension, more emotional afterimage.
Together, they make Maomao's growth feel less like a simple upgrade in intelligence and more like a slow education in human opacity, political aftermath, and knowledge that refuses to disappear.
FAQ
Does Maomao see Shisui as a real friend?
Yes, but Maomao expresses friendship indirectly. She is more likely to preserve details, notice inconsistencies, and remember the person through action than to call the relationship sentimental.
Is Shisui's cheerful personality fake?
Not completely. The Loulan reveal makes the cheerfulness complicated, but it does not automatically make it false. A mask can still contain real habits, real preferences, and real moments of relief.
What does Shisui leave Maomao in Light Novel 5?
She leaves more than a memory. Through insect-related drawings, field-guide clues, and the later trail toward Suirei, Shisui leaves Maomao a form of knowledge that keeps affecting the investigation after Shisui herself is gone.
Why does the locust threat matter so much?
Because locusts can devour crops and turn field damage into a national crisis. If harvests fail, food supply, tax stability, military logistics, public order, and the political survival of Li are all at risk. Shisui's insect knowledge helps Maomao understand that tiny signs can point toward country-level danger.
What is the biggest thing Maomao gains from Shisui?
Maomao gains the understanding that people leave traces in more than words. Shisui teaches her that affection, disguise, survival, and careful observation can all survive inside the same unfinished trail.
Should anime-only viewers read this article?
No. This is a light novel spoiler article. Anime-only viewers should wait until Shisui's identity and the larger consequences around Loulan are fully revealed.
