Dose anyone know the manga where uke thinks he is the one died and is the clone and because he is clone that's why top dosen't love him and treat him aggressively in bed but at the end it turns out it was top who was dead and is clone of the dead top.

There was one line uke repeat that "there is no seat for me in heaven because I'm not the owner of it I'm a clone" something like this
PLEASE LET ME KNOW if someone happens to know
