Just my thing RED FLAG SEME

Yep waited until latest chapter to decide where to put him. This is a BL btw (u might get confused bcoz of the covef)

Spoiler
He just wanted revenge, make the uke fall for him and leave him (uke ghosted him) Pretty sure that plan will backfire

this is not a typical red flag seme which is an asshole that regrets, the seme is just really creepy (obsessed) to the much younger uke that he met when the uke was like, 10. (though he approached uke when he turned the proper age)

still weird

but i've added more morally questionable stories here so i think this one is kinda light
