AHAHAH finally someone else who has seen "You're Beautiful"... Watched it with my siblings some time ago and was yelling at the screen all the time bc omg the melodrama... I recall hating the main male lead, he was legit SO mean to the female lead for no good reason XD.

I recall enjoying Coffee Prince back in the day. If you want another "Guy goes through a whole gay discovery journey before learning his crush is secretly a girl", that's a big plot point for the second male lead in Hana Kimi, which has a Japanese, Korean, AND Taiwanesse adaptation (and was originally a manga). I can't remember if the adaptations particularly differ in how they handle it, but I recall tearing up and feeling strongly for the secondary male lead throughout...
