I think it was shoujo, but I think the main guys family runs a shrine or something and they're cursed? The guy cant date or be with anyone because hes engaged to some dead lady because of a curse for when a Male is born in the family, but he ends up liking this one girl and so I think his family brought her to the shrine and use her as a body to house the spirit of the dead women in the underworld. The guy finds out and saves her but in return he gets dragged to the dead ladys place? Please help me. ╥﹏╥
Yaoi about a blonde guy owning a shop and a new doctor moving into town? The blonde guy has a daughter too.
I think its this one
