Niki's manga / #Psychopathic yandere Seme(1)

SPOILER There is an "official" couple - seme (Choi Yule/Yul-ah) x uke (Ha Kyung-soo). Yule is a psychopath. Kyung-soo is a very unfortunate being who gets raped almost everytime. Yule has older brother (Choi Geon) and sister (Choi I-Yeon). This family is obviously rich and full of messed up people. There is this other dude (Dong-hyuk) who loves Kyung-soo. THE WHOLE STORY IS FUCKED UP. Kyung-soo works at a convenience store and has a rather peacfull life. He gets attached to Dong-hyuk who is a regular customer of the shop. He confess to him and they start to go out. But Yule, who is CLEARLY a psychopath and Kyung-soo's ex-boyfriend, shows up, rapes Kyung-soo before Dong-hyuk eyes and takes Kyung-soo with him - basically kidnapping him. He fucks aka rapes him a lot - to break him. Then he is summoned by his family to the family mansion so he takes Kyung-soo with him. But Yule has a fucked up familly too. His older brother is messed up thanks to Yule - to the point when he rapes and beat up every single sex partner his little brother ever had just to make his little brother angry. Their sister is obsessed with her little brother. She even kidnaps Kyung-soo, when he got away, so he can be fucked by Yule. Yule managed to change Kyung-soo to an obedient sex toy at this point (basically) - he even used his brother's sadistic desires (he aka brother raped Kyung-soo and beat him up so Yule could see). Then he leaves the mansion with Kyung-soo. Kyung-soo runs away and meets Dong-hyuk who changed after witnessing the rape of the Kyung-soo by Yule. They start to go out but Yule shows up and takes Kyung-soo away again. Kyung-soo tries to distract Yule with his own body and sex so he would leave Dong-hyuk be. But in the end, thanks to Yule's brother, Dong-hyuk manages to get Kyung-soo back. The ending is almost a dead scene. Dong-hyuk takes Kyung-soo out so they can confront Yule (and his 2 bodies cause Yule is a psychoptah who can manipulate people and leads a gang). Dong-hyuk takes out a knife and helds it on Kyung-soo's neck telling to Yule that if he really loves Kyung-soo he would kill himslef cause if not he would kill Kyung-soo to free him from Yule. So Yule stabs himself. In the end they all are alive. Kyung-soo starts to work at the convenience store again. Dong-hyuk lives his own life. Yule meets Kyung-soo outside - and that's the end. I guess they got together again cause even though Kyung-soo got raped by 3 guys who were under Yule's orders in the past he still loves Yule for some reason... From chapter 71 it's the "What if" world. 71: What if Yule gets locked up in a mental hospital and Kyung-soo hooks up with his older brother. 72: What if Yule gets locked up in a mental hospital and Kyung-soo hooks up with Dong-hyuk. Chapter 73 is an epilog for the main story when Kyung-soo lives with Yule and Yule is trying to appeal to Kyung-soo. I can't really rate this... I didn't dislike it but I didn't really like it either. It's just... fascinating... in its on way.
