Ochiru Seija no Seppun
1-2: student seme x teacher uke. teacher got caught by seme liking to be groped on train and has since then blackmail him to become his slave. seme actually liked uke to be his slave target since he first saw him. 3-4: seme gets heart burn for no reason when he sees uke looking at tokiwa (previous chp seme) with hot eyes. he began bullying him and making him his slave after uke peeked at tokiwa having xxx with sensei (previous uke). seme came to like uke but pushed him away as he is afraid that he will leave him because his family is broken. 5-6: teacher seme x student uke. uke hates seme when he thinks seme is homo because uke had a bad memory about his past, being raped by a guy made him homophobic. but uke with seme feels different so he eventually accepted seme.
Kyou Kara Dame Inu!
