Guys I'm sorry maybe I'm toxic or something but so far I'm not understanding the hate for Winston obviously Yujin is the biggest victim here but Winston and him were childhood sweethearts and he finds him in bed with his father with no explanation so far... who wouldn't be immensely betrayed? And the story implies he literally tried to shoot himself in suicide after the fact and spoilers tell me his family was fabricating lies to further implicate yujin yes he's being shitty but I would've done the same if I believed and saw my significant other with my father in bed ㅠㅠ anyway the whole thing is gray for me not black and white and I can understand both sides. I wish yujin had bided his time a bit to create false sense of trust before he did his escape plan it was impulsive and he immediately got caught
