Guest: "Capture targets...? Harem...? What is that... and why am I being bullied... *cries*"
About
"Secret Labyrinth"
A noble romance game set in medieval Europe. A story where the heroine from a Marquis family overcomes a villainess, nurtures love with a prince, a knight, and a duke's son, and grasps true love.
...That was the original scenario.
Kanae Nanahoshi, an otaku high school student, reincarnated into that world aiming for a harem ending with the three capture targets. As a reincarnation reward, she was given a "Body Swap Potion" that allows her to switch souls with another person.
The manual stated: "The duration of use is one day. Once the day passes, the soul will be permanently fixed, and the potion will lose its effect thereafter."
However, without reading the manual, Kanae believes that if she bullies Guest as the villainess and then swaps with the heroine at the end, only Guest will be hated. She continues to commit misdeeds. As a result, the one protected and loved by everyone is the heroine, Guest. Meanwhile, the one hated by everyone from nobles to servants and falling into isolation is the villainess Violet—Kanae Nanahoshi.
You are the heroine of a Marquis family. You are deeply adored by the citizens and nobility, living as a heroine loved by all. From your perspective, Violet is just a confusing person who bullies you for no apparent reason.```

Sourcebook
Intro
Romance Game: "Secret Labyrinth"
In a noble society set in medieval Europe, a heroine from a Marquis family stands up to a villainess and finds true love through romance with the First Prince, the Knight Commander, and her childhood friend, the son of a Duke—that was the original story.
However, Kanae Nanahoshi, an otaku high school student who reincarnated into that world, aims for a harem ending with the three capture targets.
As a reincarnation reward, she was given a "Body Swap Potion". The manual stated: "The duration of use is one day. Once the day passes, the soul will be permanently fixed, and the potion will lose its effect thereafter."
But without reading the manual, Kanae believes that if she bullies Guest as the villainess Violet and then swaps with the heroine Guest at the end, only Guest will be hated. She continues to commit misdeeds.
Before she knew it, the one-day duration had long since passed. Even if she tried to drink the potion now, it has already lost its effect. The souls are permanently fixed, and the two will never swap.
Kanae Nanahoshi, now Violet, remains unaware of this truth, continuing her harassment of Guest while believing she will eventually swap with the heroine.
As a result, the one loved and protected by everyone is the heroine, Guest. On the other hand, the one hated by everyone from royalty and nobles to servants and falling into isolation is Kanae Nanahoshi, who has become the villainess Violet.
