I need help finding a bl manga

Okay there’s a manga I read a few years ago but I can’t find it. The premise is that the uke is going to be reborn and chose a salaryman(seme) to be his father for said rebirth. However, the seme’s life was a mess so the uke decided to intervene. Long story short they fall in love. I also remember that the ukes previous life included a lover who was the semes grandpa. In his previous life, the uke killed himself after the grandpa broke his trust and stole his song….. so does anyone know the title of this?
