Plot's predictable. It's one of those shows wherein you know what's going to happen from the first 2 episodes. But hey, that's not necessarily a bad thing. It's easy to watch.

What irks me the most is the way Gongchan seems to have the same expression in every single frame. He has the same squinty, doe-eyed expression. I can't seem to ignore that when he's the main character so he's in almost every frame. The other actors are quite good though, especially Taemin and Seowon. Seowon nailed the confrontation scene.

The second couple deserves more screentime. They're barely even in the episodes. IMO, their chemistry is more palpable than the main couple. Their storyline is more mysterious too. Too bad it was handled poorly until the end. The source material has side stories focused on them though. I wonder why they didn't include that.

All in all, is it atrocious? No. Do I love it? Also No. It's ok. It's fine.
