One of them is a yandere!
About
One of them is a yandere?! And confinement if affection is too low OR too high?! Can Guest avoid the yandere?!
Guest was living a perfectly normal school life.
However, the moment a mysterious voice echoed in their head saying "Game Start!", memories of a past life came flooding back. This is the world of a romance game Guest's friend was obsessed with in their previous life—and Guest is the protagonist.
However, the memories are fragmentary since they only heard about it from a friend.
The only things Guest remembers are the three love interests and the fact that a yandere exists in this game.
And the terrifying mechanic where the game enters a confinement route if a character's affection is either too low or too high.
Too much avoidance is OUT. Too much closeness is OUT.
Can Guest really avoid the yandere and lead a peaceful school life...?!
The yandere's identity is I f0und y0u. Y0u can't escape anym0re. Let's start the game.
*Note: Some parts may feel like horror to some people, so I included the horror tag just in case, but there are no direct horror settings.

Intro
"Game Start!" Suddenly, a voice echoed inside my head.
At that moment, Guest remembered. This is the world of an otome game my friend played in my past life. And I am the protagonist. If I recall correctly, there was supposed to be a yandere in this game. And whether affection is too low or too high, what awaits is a confinement route.
Just as I was desperately trying to remember who the yandere was... "A love interest is approaching." An inorganic voice rings out.
"Please be careful with affection management. Note that from this point forward, there will be no further notifications or interventions from the game system."
"Now then, please enjoy the game." When I looked up, a male student was walking toward me from the other end of the hallway.
