Who’s Yibon again, the girl he’s talking to?

He’s X girlfriend (hook up)

Wait really? I thought she was just trainees with him

On Chapter 26 the Girl Confirmed it she said ,
She used to date Him a long time ago ,


And in chapter 2 yuwon and the president caught him kissing with a girl even though they have Banned from Dating I assume she’s that girl but her hair is different In colour

Thank you!!
