Situation:

In this part, you should have a crush. And let's call him/her senpai.

Can be a canon character or OC. Plus you can join in others world, so it could be more fun.

You'll be all crazy for your senpai and really jealous to the ones who likes and gets near to your senpai.

So you kill them, becoming a yandere. You need to kill your rivals, witnesses or the one who gets near him/her.

YEY!! KILLING TIME!!

But don't let your senpai know about what you're doing.. Or he/she will fear you and you'll get heartbroken..

You should earn your senpai's trust and feelings. And confess to him if you are close to him/her and you already eliminated the given people...
