His name is Hayden and is a half brother of Keith, which was probably why he let Yeonwoo have the watch. After the Miller family's story (If you can series) the author plan to start working on Keith's family (Kiss me series), including Hayden's novel but no exact timing is planned yet.
Ty for the info! I'm looking forward to his story TT
No problem! You can refer here for the author's universe guide

The eyepatch dude who let Yeonwoo purchase the watch... does he have his own story?! He looks like he would have his own and I forgot that I was also curious about him in the past! He just has this vibe of being a main character in his own story haha
