Same here.
I called it when he showed up and I am sure this'll just be another 'misunderstanding a job offer for flirting' trope kinda arc. It fits Yiyoung in misunderstanding things and ending up in awkward situations. So when it's revealed there'll be an option for another hilarious freak out moment for him. XD
They did not have much interactions yet, so I could be wrong.
This author goes for more relaistic storytelling so maybe if they get more moments alone it'll start to show.
They ARE shown on the cover art, all three of them, working in the office tho. So I'd rather bet on my guess.

Who doesn't see the love triangle thingy? Like idk there's no spark for doyeon and yiyoung. If there will be a love triangle the author should put a drama now but there's nothing yet. Yiyoung is so head over heels to Director Kang.
Anyways director kang is still an ass. like why do you say that?
