Couple of things:
1. Don't watch it after you watched Skate into Love and are expecting a similar exciting drama.
2. Don't ask questions, use logic or think. Just imagine that your brain is hibernating. Otherwise, you won't enjoy the drama.

Okay, so it's kind of a cliche drama with a ludicrous plot that is improbable. However, if you accept the fact that it's kind of like a fantasy fairytale, you can enjoy the cliches, the sugary sweetness and the cheesy goodness that this drama offers.

The acting is really good!
The ML is absolutely adorable and very cute when he's naughty/plotting things. The FL lead is equally adorable and entertaining.

The story is just so-so. The actual sports scenes aren't shot that well. The hockey outfit is very unflattering on the ML. The premise is silly and hard to digest (even if you consider it fantasy).

There's no theme or concept worthy of mention.

Like I said, it's a guilty pleasure drama that you see once and deny you know it. ??
