What is the name of this yaoi manga?

I remembered this yaoi manga I read a while back and I really want to read it again but I can't remember the name of it for the life of me. It is about this younger boy who is abused at home by his mom and dad. One day he's on the streets or something and an older man invites him to stay at his house, I think. I don't really recall how the boy got there or why he went. But I do remember that the older man was very kind and had a younger daughter. His wife had passed away a while ago. I remember that the younger boy goes snooping in one of the rooms and finds a box of pictures of the man having sex with his late wife. Eventually the man saves the boy from his abusive parents and they make love and its all really cute. It would be a huuuge help if you could tell me the name of the manga!! Thanks
