Basically seo-in is adopted and was terrorized by his ‘brother’ jaewon. This continued for years and seo-in would follow anything jaewon asked of him because jaewon blackmailed him with info on his biological parents. Jaewon meets Yeongwoo during judo, I think they’re rivals kinda but yeongwoo is nice to Jaewon and that pisses jaewon off. Seo-in noticed the rage yeongwoo brings out of Jae won and wanted to use that to his advantage basically. Prompting seo-in to introduce himself to yeongwoo as his “fan” when really it’s to get back at Jaewon. Keep in mind in the present, Jaewon is dead.
Thank you so much, you’re an angel
Can someone please explain the flashback chapters to me, I’m so lost
