i think, it's the stalker from their high school days and if i got it right, he and minyoung had a deal - meaning jae hee sent countless photos of cheol to minyoung over the decade, he and minyoung weren't tgt.
Damn i thought minyoung would have already eliminated that guy by now
i mean, as u can see on that photo wall, he was useful to minyoung and unlike cheol's father and brother, the stalker wasn't a threat to cheol. oh and also looks like he is going to get rid of him soon, since minyoung doesn't need him anymore, now that he's with cheol
Who was jae hee again
