It was ABO novel. I forgot Uke's identity. If my memory not messed up, Uke's identity iis higher than Seme. What i can recall clearly that Uke likes Seme, yet Seme has someone he persue. Uke who likes Seme try to get close to him and earn Seme's trust. One night, Uke's heat come up. He hid in the room. Then Seme found it strange, call Uke, find out about Uke's, heat, then come to Uke's room. There Seme offer his help. In the middle of it, Uke carried away by atmosphere try to kiss Seme but Seme immediately refused him. Uke who is heart broken cry and try his best hid his face wit pillow and restain his sobbing. Actually Seme knew Uke cry at that time since he tease Uke for cry when the do it. Actually i forgot wether it was novel or manhwa. Good soul, if you happen to know what novel's title is this or familiar with it please inform me. Thank you.
