I'm not the person ur referring to but this arc really is good. I'm gonna spoil EVERYTHING in this arc so be careful I mean from the roof to the basement floor so BEWARE
Shj is laying his chin on hyj's head as hyj confronts shj why he isn't invited. shj saying "you don't need an invite because your my item" and then in the birthday party itself, shj and hyj having a heated fight before shj becomes a gentleman.... And then some circumstances happen and 1/3 people sing happy birthday for shj and the only one is hyj who bought the cake...? (Wasn't a cake but they had to make do) and lit a candle in a Korean convience store lol ╮( ̄▽ ̄)╭

If you love the hyunjae yoojin ship you will LOVE this arc, this arc sold me on their chemistry it is AMAZING. I hope the manhwa does it justice cuz I'm so excited
