I'm looking for a Japanese manga that I read a long time ago.
The story is about the seme and uke living in the same house. The seme is married to the uke's older sister. Even though the older sister has already passed away, the seme still continues to live with the uke.
The uke has secretly been in love with the seme for a long time. The seme also seems to have feelings for him, but he refuses to acknowledge or admit them.
I remember that there was a garden in the backyard with a cherry blossom (sakura) tree.
If anyone knows what manga this is, please let me know! I've been trying to find it for a long time.
