[m]Ok so its about this guy (of course) and since he was young he had this teacher but somehow they became lovers as he became older. Ever since then the teacher has been really possessive, at one point he even sorta kidnaps him. But the teacher is also helping him prepare to take over his fathers buisness, which by the way is big. I think some people are even afraid of the teacher? OH! and the teacher works at the buisness in a high up poision. Please help! Remember the teacher is possessive of his lover. 😕

I don't remember from which manga in the series that particular plot is from but I think the manga you're looking for features the couple from this manga: Oboreru Kemono no Koibito
