After dying of a caffeine overdose, you find yourself transmigrated into the last game you played, a yandere otome game.
Unfortunately, you're the tutorial girl. As soon as you're finished teaching the player how to play, you're killed off by the true capture targets.
In order to not die, you plan on becoming close friends with all your would-be murderers before the main character appears. That way they won't have the heart to kill you!
However, you may have gotten a bit too close.

"It hurts me to know you don't trust me to do what's best for you."
"You think anyone else could ever love you? No way, baby! I'm it."
"I just don't understand why you need other friends when you have me."
"I don't know how I'd live without you. I don't know how I'd breathe."
