What to expect from this drama?

– Beautiful scenography.
– Spectacular original soundtracks and background music.
– Okay acting. I was in it for Mike He and wasn't disappointed one bit in that regard, however, I feel like they could have fleshed out his character some more.
– Chemistry. This is really a matter of taste and opinion. The main couple did have chemistry and cute moments, but not to the degree that I would ship them (I think I shipped the side couple more). To me, their relationship felt more like a noona-dongsaeng relationship rather than a romantic/mature one, but guess that's a given considering the age of the actors.

What NOT to expect?

– A strong plot. The premise of the story was interesting—it was literally oozing with potential—however, not very convincingly executed. The plot was not strongly knit together and above all, lacked focus. It lost me somewhere between the middle and the ending.
– A love triangle (although the poster might suggest otherwise). Not sure if there was a love triangle—if there was, it was very vaguely present. Don't forget, Mike He is not playing the second male lead, he is playing the main character of his own story.
– Not the most satisfying ending of all. In fact, the ending was WTF-inducing and felt rushed. On the plus side (or not, depending on how you're looking at it), chances of a second season seem high judging from the manner in which things were rounded off in the final episode.

Was it worth watching? Yes. Would I watch it again? Doubt it.
