Yandere/Obsessive Male Leads (and sometimes FL)

About a gurl pretty much a granddaughter of yakuza and this guy with a lot of emotional damage and he only lives to protect her and he’s unhinged but like she loves him too so its fine. They just both don’t realize it. Cute and funny, age gap a bit but like japan sooooo it could be worse. Only by like 10 years but she is still technically a minor…. It’s fine it’s fine…for a manga

ok so the FL doesn’t take bull so shes like, more aggressive sometimes but the guy is like “step on me” but like he’s obsessive of her and like, cant have anyone but her but he’s like “i want to b ur slave” and shes like tf u said? It’s pretty funny and not the usual for me but sometimes changing things up can be nice
