Basically we got a flashback in the earlier chapters of Seo-in “brother” (forgot his name) assaulting Yeongwoon with his friends and breaking his arm, and that’s why Yeongwoon couldn’t come see Seo-in off before his flight. Seo-in didn’t know about that and thought he didn’t come bc he didn’t want to so the real reason was a shock to him. I think he’s probably gonna feel too guilty to continue staying by his side

I’m lost… I’m so confused. Can anyone help explain… thank you
