Comment by I have BL novels on Non Zero Sum - Chapter 36

After that incident, the other two friends blamed Haeyoung for causing Haewon to jump off the cliff because Haeyoung tortured Haewon so badly. Until the end, the two friends thought Haewon was dead, only Haeyoung didn't accept and believe it (but before Haewon's suicide attempt from jumping the cliff, Taegyeom and Hyunwoo had apologized to Haewon before, only Haeyoung had not apologized). After losing Haewon in that incident, Haeyoung then became depressed and often began to hallucinate. He also harmed his own body, frequently cutting his hand, and there was a time when he poured boiling water on his own hand when he hallucinated and his hand became so ruined. He actually only realized his own feelings when he lost Haewon. He had mental issues where he didn't understand complex emotions like love, etc, he also has impulsivity that is inherited from his family, where he has difficulty controlling his violent urges. And after a long period of time, Haeyoung kept looking for Haewon, and he finally found Haewon in a village. He stayed for some time there to apologize to Haewon. There, Haeyoung also harms himself to make Haewon forgive him. Haewon eventually forgave him because he saw that Haeyoung had suffered enough. Haewon always has a soft spot for Haeyoung, as Haewon always remembers Haeyoung as the only person who was always there for him during the hard times back in the day. In the end, Haeyoung confessed his feelings to Haewon in his own twisted way, and they ended up together. (In the side story, they lived in peace as lovers after that. Haeyoung takes Haewon to therapy and he also treats Haewon better. Haeyoung also tries his best to control his impulsiveness towards violent urges for Haewon's sake).
