"I won't say I love you but only you are allowed to touch my body"

Seme worships uke. Uke won't admit that he likes semes but get jealous when seme found another love interest.
Later on, uke accepts the fact that he loves seme.

Uke won't say he loves seme, but said, "You're the only who allows to touch me and see my body"

Childhood friends. Uke reunited with seme when they're in college? Uke only considers seme a friend, but even after knowing seme's feelings, he still let seme get close to him, and kiss and touch his body. Kissing second ml by accident makes him angry, but kissing seme is ok.

Uke shows his love by action. His love is believable.

Uke didn't say he loved seme when asked, just responsed by sex. A little unsatisfying.

Mutual pining at the end. Very sensual sex scenes. You can see their yearning through their eyes.
