Ik all smut kind of made everything confusing but I’m here to help!
Chapter 1 shows how Seo Seungwon (MC) sees every one as a piece of paper, a fake relationship he was forced into when he was reincarnated into this life. His brown haired classmate, Woo Jimin, is the protagonist of the novel MC was reincarnated into and only met MC’s brother, Seo Seungjun, after Seo Seungwon killed himself. MC is worried them meeting earlier than they’re supposed to could have bad consequences even though he met Tae Seongjae (ML), earlier than he should’ve too.
As to why the MC reacted the way he did is because
1. He doesn’t consider Seungwon himself and by extension doesn’t consider Seungwon‘s family as his own and
2. Seungjun’s attitude towards the ML when he not only came unannounced but was extremely rude towards MC’s boyfriend (? Idk if they consider themselves dating, I forgot if they had that conversation)
Basically he’s tired of what is essentially a stranger, someone the MC doesn’t even acknowledge as real, barging into his life without his input and potentially damaging the integrity of the original novel and it’s storyline.
