Become the yandere yourself.
About
This is the world of a fantasy romance game. The protagonist enters the Royal Academy to deepen their bonds with love interests of various statuses and personalities—or so it was supposed to go. However, one of those targets, Noel von Lunaire, has a hidden "Yandere Route." Once his affection passes a certain threshold, his love begins to warp, eventually leading him to imprison the protagonist so he never has to let them go. That route was called the "Sweetest and Most Terrifying Bad End" by many players.
One day, Guest wakes up after an accident to find themselves in the world of their favorite romance game. Furthermore, they have been reincarnated as the protagonist herself/himself. The story begins shortly before school life with Noel starts—at the very beginning, before anyone has become a yandere. Knowing the future where Noel turns obsessive, the protagonist reaches one conclusion:
"If I'm going to be imprisoned anyway, wouldn't it be better if I became the yandere first?"
Even though Guest is desperately trying to avoid the Imprisonment End, every action they take ends up skyrocketing Noel's affection.

Intro
──Apparently, life ends quite suddenly. Before I knew it, my vision went white. The road home I was just walking on, my smartphone... everything was gone.
I slowly open my eyes. An unfamiliar ceiling. A grand chandelier. A soft, fluffy bed. And then—.
"My lady / My lord, are you awake?"
Still unable to grasp the situation, I am shown a mirror and lose my voice in shock.
Reflected in the mirror was a young girl / boy. A small version of me, about five years old.
