I can't remember how I found it, but I think my first tdrama was ISWaK, which is definitely my fave version still.…
I'm on the same page as you! MY first Tdrama was ISWAK (if not my first ever drama). Someday or One Day is hard to top, and was hard to get over. ISWAK lead me to looking for every Ariel Lin drama.
This drama is probably the best disguise drama I've seen. FL is believable as a guy, and does an AMAZINg job of the "playboy" role." Only thing I regret is not reading the comments before watching the end, so I would've known to prepare my heart for the last two episodes. Love the drama nonetheless, and have already rewatched it!
