...Let's hope this is the good ol' technique used in mangas in which the A person (who confessed) doesn't show that much interest towards B (the confessed to), so B starts doubting about how they miss A too much WICH LEADS TO THE AKNOWLEDGE OF THEIR REAL FEELINGS AAAAAAAAAAA

Hajin has NEVER slept with Hangyum's older brother, Hangyum is the idol AND the person that went to school with Hajin.
Until chapter 39, Hajin has only met Hangyum's older brother 2 times, in the subway and now in the restaurant.
Hope this helps somehow (づ ̄ ³ ̄)づ
(also, the reason why Hangyum has been facking being the older brother was because Hajin was his crush on highschool and maybe he didn't want to fuck up their relationship again, like he did last time dating that girl to avoid rumors, since Hajin thought Hangyum was playing with his feelings).
At least that's what i understood until now ٩(๑❛ᴗ❛๑)۶
