Hi! I'd like some help in finding some mangas where the seme is a bit scary. Scary in the psycho sense. Something a bit like that yaoi series where the seme is a yakuza and the uke was the teacher of his son. The yakuza tried being sweet and caring but when the uke pushes him too far he can be almost abusive (seriously threatening to cut up your love?"!). Borderline-abusive recommendations are also appreciated.

It might be - Houkago no Love Call by Kitazawa Kyou
