Wait what chapter did he appear in omega complex

He didn’t appeared, if you’re talking about the mc. He was just briefly mentioned 2 times in omega complex. The 1st one is when they have street food booth, and the 2nd one is in the side story when Dohyun didn’t made it in their bbq reunion.

Ohhh okay got it thanks

I'm really not planning to read the first one. Care to share how was he mentioned? And what about the ML? What role did he had?
