Does anyone know what bl is this?

1. This is a manhwa. The mc (uke) initially worked in a restaurant (not a modern restaurant) but then he was fired, because the restaurant owner found out that the mc had a relationship with her daughter(I'm not really sure with this because I don't really remember) Then someone suggested him to work as a teacher in the mansion on the hill. There he met the ml, and I forgot how the story went. but there was a moment where the ml killed his father, then had sex with the mc while holding his father's heart. The mc has black hair, and ml has blonde hair. And as i remember this story only have 10 chapter

2. This is also a manhwa. The mc(uke) and ml were dating. But then they broke up, I forgot why. And then the mc turns into a wolf and meets the ml again and the ml keeps him as a pet. It looks like the wolf is black. And i think they're actors or college students. This one have maybe 39 chapter
