This chapter had so many things that just give a bad feeling,
stalker being terrible and getting away with it,
MC being a pussy,
people talking actual shit about others for no reason,
something from someones past comming up like it's obvious that classmates would know MCs "mistake" from years past,
sister falling for random guy before sufficient plot,
sister being way more ditsy than reasonable just to make it easier to make her a damsel in need of rescue.
It's too much feel bad shit in what should clearly be a feel good comic, dropping this shit.
