Yoonseol is actually gay, he's been shown very clearly to have male sex friends. Only the cleaning boss is straight (and he seems to be quite sexually and romantically inactive) so it is a hurdle to pass for him to be in a couple with Yoonseol.
Imagine if the manga readers were in the manga world? ╥﹏╥
"yea we got a gay couple having seggs in the hotel room 203 at 3 o'clock, oh wait no they were straight guys. I REPEAT THEY WERE JUST STRAIGHT GUYS."
