Spoilers!!!
Read at your own risk,
Some niggas are weird asf for making the most normal things appear weird for no reason,both of them are adults now , and they didn't know each other since childhood, they met when Wooyeon was a middle schooler (16 y/o) and Dohyun was a freshman (20 y/o). Wooyeon started having feelings for Dohyun, and Dohyun, realizing this, felt guilty. Knowing it wasn't right since Wooyeon was still a minor, Dohyun maturely stopped tutoring him the day after rejecting Wooyeon's confession. Four years later, they met again as adults. Dohyun's platonic feelings began turning romantic, and he knew it was Wooyeon from the start. Not wanting to make Wooyeon uncomfortable, bro waited for him to confess, which Wooyeon eventually did.so yeah that's what happened lol

Just curious. Why is 20 considered taboo if teacher is 24? That’s the American equivalent of a freshman and a senior, but they’ve known each other since childhood so idk?
