Please help!

Not sure if you mean bl, straight, or gl. But i'll just give a recommendation for all of categories.
Straight; My student can't be psychopath ( I'm not sure if you can consider the yandere as the mc but he is the ml, so he sorta mc...? This one is a manhwa btw ╮(￣▽￣)╭ )
BL: Color Recipe ( BE WARNED THIS SOME CRAZY SH*T
