There was nothing particularly wrong with this Drama, and enough that was right to make finishing it worthwhile. The OTP was cute enough, though their clicking seemed a bit sudden when it happened. The mystery was also ok, I've definitely seen much worse. I give the Drama credit for what it put the male lead through in the penultimate episode, it went somewhere I wasn't expecting.

The downsides were the annoying clownish tutorial head teacher whose past caught up with him, and the show's determination to basically just say "forget the past" for some pretty industrial-level betrayal and deceit. Said betrayal was obvious early on, the big reveal was "yeah, saw that coming from episode 2" kind of material, but the journey to that point was tolerable. The second leads were a big part of the reason for that, their arc was more nuanced and more crediblw than the leads. Finally, I love the song used for the OTP, "Siren Song" by Three Laws - a keeper for sure
