There is this school that at the start of the semester, cards are hidden around the school grounds and students who find spesific cards are given a role and this event creates a hierarchy at the school. Our main character(uke) is a blond pretty boy who is quite popular and attractive and has the "king" role. He is basically the king of the school and spends most of his time in a room in the school and has a lot of influence. He is quite flirtly with everyone and most people want to be close to him. Despite his popularity, he has a tragic past and endured lots of abuse so he is traumatized person (i dont remember his past). He lets other high rank dudes bully people with weaker roles. (There is also a queen but she has power among girls i guess). The other main character (seme) has dark hair and basically one of king's sidemen. He is sexually attracted to uke and especially weak to his flirting. There is a new card hunt so, uke tells seme to find the king card again but he betrays him and gives him the worst card (ace?) while he takes the king card. After that uke techically becomes one of the bullied kids but seme has him beside him most of the time in the room. Most of the time seme has sex with him forcefully but after a while, uke just gives into him, especially when seme is gentle he gets emotional because of his trauma (as in he doesnt deserve this kind of treatment because he is a bad person) But seme is not so friendly and lets other guys even sexually abuse him because uke is not obedient. And fked up stuff like that. Because of his looks and now he is weak, lots of guys wants him and etc... this part was horrible tbh. Later, there is a popular guy with a decent rank and he sort of manipulates a glasses guy (bullied) into a sexual relationship with him. Glasses guy gets obsessed with him etc. After that some really weird stuff happened regarding these 4 so i stopped reading it but for a while i am reminded of this serie. I wanna know how it ended. I read this approximately in 2015 or something sooo you know what happened back then. I tried to provide all the details I remember. If you made it all the way here i must congratulate you for your high attention span.
