Story 1 (Ch.1-3 + ): Seme and uke are together for 5 years. After 3 months of not seeing each other, seme says he got married but don't want to break up with uke. Uke starts going out with a bartender (seme 2) who listened to uke's love troubles. To properly date seme 2 uke meets up with seme to break up wiith him. After hearing that his boyfriend dates someone else seme gets angry, bites and rapes uke. Story 2 (Ch.4-5): childhood friends. Uke confessed to seme but seme said "disgusting" to him. Uke thought it's the end but after one week seme appeared at his new place. After that seme came repeatedly to uke's place only to have sex. Uke thought that seme just used him for sexual needs. The truth is seme thought they were dating and said "disgusting" just to hid his embarrassment because seme was happy to hear uke's confession. -> big misunderstanding
