attempted rape
Yumi is going out with his boyfriend, Kan, since school. Kan was abused at his job and becomes more and more agressive towards Yumi. Then, Yumi meets the guy he had a crush on before meeting Kan.
Kan has an own story, which is definetely worth reading: http://www.mangago.me/read-manga/hadakeru_kaibutsu/
SPOILER: Even though it is inexcusable that Kan beat Yumi I really liked the fact that he let go of Yumi (despite loving him so much)
Hatsuki falls in love with Watakabe, a famous, intelligent and succesfull student at his university. Later he watches Watakabe picking up a guy at the park. Some time after that he meets that guy again and sees strangulation marks on his neck... Even though he knows that Watakabe is an abusive sadist he approaches him and their abusive relationship begins. I wished that the story would not have rushed that much at the end. It would have been better if Watakabe had gone to a psychiatrist
