I think that was somehow the best outcome.... everything was pain and pleasure, guilt and adventure.... it's hard to differentiate love, and he ducked at it big fucking time. They hurt themselves and everyone. They did it for love, selflessness and somehow egoism too..
Doyeol loved his cousin more than in a familial way... and Kyujin loved him in a familial way so much that out chances and support he give in to his cousin, it was comfortable and safe somehow. Then he meet Jimin and this is new and exciting, it starts out as a joke and adventure and it turns more deep as time passes. So he is devided between 3 tipes od
Of* love, 1 is the one that he didn't start or question it, doyeol loves him and he just accepts it... jimin makes him feel desire and passion, and he risks going with it, but Jiminy goes away and he is confronted with doyeol's comfort and love for him, just waiting there. So again he gives in and starts to learn that he also loves him, in aore romantic way. And this mess repeatedly happens... because kyujin is a confused and easily lonely and ready to accept love and give love. Doyeol is so in love to the point of obsession and manipulation. And Jimin has felt love for the 1st time and don't want to let it go either. So I think it took time and many mistakes happened, but kyujin finally took action and let them both be free of this cursed cycle...
ok cause what the fuck. first of all, they are cousins and fucking, why did everyone in the story act like that was normal. secondly bro this mc is horrible and is manipulated so easily (the cousin guy sucks for manipulating him too) i honestly just want justice for jimin cause the mc literally just used him and fucked his cuz without hesitation. like bro come on. get ur fuckin shit together instead of running away from both of them. i just had the let that out lol
