Yes
I mean we still don’t know because that day was the day Seo-in left to USA and we don’t know what exactly happened that day other than his brother (seo-in’s) beating up the bottom. (Forgot his name
No. The first chapter is when they're already adults. It's not when they were kids and him moving to the US. Something WILL happen to Yeongwoon soon. The first few black panels of chapter 1 is the actual present scene. We are going through flashbacks until we reach chapter 1 again.
i saw a theory somewhere saying that chap 1 is the present and all the recent chapters are just flashbacks and that we still don't know what happened why he was bruised up in the first chap. Is that true?
