here's what I can recall:

*the seme is an idiot, his father is dead
*the uke is the seme's guardian
*the uke promised the dad that he will take care of the seme
*the uke is very strict
*there was a scene where the uke went to the graveyard to ask permission from the dad that he wants to be in a relationship with the seme.

thanks

It's Oni ni hatsujou.
