I'm so confused who is this blonde dude. I don't remember him

he's kyungsoo :) hyesung's friend!

I think thats Hyesung friend. I recently just finished reread this and i remember Hyesung having a friend

Hyesung's mama; Dojin's mother-in-law
ヾ(❀╹◡╹)ﾉ~

I had completely forgotten about him! They never mentioned him again after some point. He was a great friend to Hyesung :(

Yea, he was a nice dude but the author was focused on thier love story that they didnt have time to gice him some screentime

well now we have it hahaha
