Seme & uke have student-sensei relationship. Seme make asked uke to have sex, they did, but only uke caught feeling for seme. Seme just having another relationship and come to uke when he want to have sex. Seme knew that uke liked him and took for granted. He never make an effort to build anything with uke. When they meet again, it's just a convenient they become together again. Seme get away that easy.
I really want seme to suffer ( ̄へ ̄)
