someone pls give me spoilers :D

I read a spoiler

That the pink hair girl is obsessed with ML and is a stalker
ML did not like her - but he didn't report her since she's his old teacher's daughter and he let her off due to the respect he has for the teacher
She tries to get in between them but I think the spoiler I read also mentioned that the ML deals with her

And his ex is some other girl, not this stalker one

omg thank you :D
