when she says
really? this boy, i wonder if he... would really kill me...
well you said it he a yandere!! you just say that he kill the heroine just because she couldn't accept what he did and got killed. imagine if it happened to you!
you do not know how the heroine will be with you and the other guys try to flirt oh hurt you, these are problems.that could wake a yandere! ( ̄∇ ̄")
you know you just dug your grave when you said- "you have the freedom to decide for your self, both in heart an body. never forget that, okey?".
me: well is nice what you did but (❀╹◡╹)ノ~..
he could use those words against you woman! Σ(っ°Д °;)っ one mistake and you are dead. oh maybe the boy is not so bad. but, it's still a yandere ,I've seen several types of yandere and it worries me. ╥﹏╥ but good if I'm very interested in this story but I'm still worried because yanderes are not easy.

Yandere is a personality trope in fiction but not a real concrete sure thing to happen. It's not like someone is born a yandere. The other capture targets all probably have messed up lives and deteriorated mental health to commit the crimes they did. But Ashley is growing up now with someone who's teaching him healthy mindsets right away. I think we are now more likely to see 2 Completely Normal People navigating through a school full of psychos. That would be comedic if anything.
"Are you the demon lord?"
me: are you the stupid one?? ヾ(❀╹◡╹)ノ~
