Um no I don't see why they should out themselves to someone like her who they are not close to. They can simply say they have love when they are asked about it. However, Jihwan could have told her that Jun had a lover but I think he didn't think she was serious at first, only wanted to be friends. By the time he realized she was serious, he was confused and didn't have time to sort out his feelings, confused whether to say something or not.
Also, She did not ask Jun if he was single and decided ON HER OWN to confess on her bday knowing she could e rejected. So... she's playing herself really
Everyone falling for Junnie is UNDERSTANDABLE!! Tbh, he has the best character development throughout the manhwa. I just wish Jihwa tell chae-ah honestly first when he have all the time in this world to be honest. The fancy restaurant booking and being rejected on her birthday is the last thing she deserves!!!
