the title??

Help me find this.
The story like this the seme and uke are childhood friends but the uke is prohibited by his father to go outside their house. Then the seme left for Tokyo I think only to know years later that the uke died and was killed by his father. But the uke sent a letter with a clover inside before he died. Help me please. I remember it's just a oneshot inside one manga ...
I read this coment in manga and really want to know the title..
