Yup he's fully denial . >_> plus he simply can't imagine Haesoo attracting another man since in his opinion she's too old, she wears grannies clothes, incapable of talking to other guys, too messed up financially and background wise to attract any decent guy around. Thus even if he saw the guy with hickeys etc Haeso being the one doing it is the last thing he'd assume.

Did Michell forget the time he found the other dude in the house half naked pretty sure he had hickeys too and condoms were everywhere and they even had a fight?? Like why does he refuse to believe she been hooking up with someone else is he that dumb
