This drama is the cutest, lightest drama I've watched in a long while. While it is very distinct from Love 020 (which many people compare it to), the feel is very similar even though the story is very different.

What I loved:
- The series grabs you from the get-go (unlike many that drag at the beginning)
- The female lead has an actual brain. And so does the male lead. You don't have to put up with any airheadedness on either side.
- The story is just sweet.
- The characters act like real humans. Nothing seems super overblown (except maybe the parents, but, ya know).

What I didn't love:
- It seems like the writers just forgot about characters as it continued. No explanations, just gone.
- It could have been seriously shorter. Did we REALLY need to watch a dozen swimming competitions? Probs not.
- There were a lot of moments when it felt cheaply made. There were just a few sets, and it was noticeable that they were just trying to make it work with what they had.
- The characters were dubbed, and they definitely didn't kill themselves always making the lips match perfectly, especially with 2 (minor) characters.

Rewatch value:
I would definitely rewatch it, though I might make ample use of the fast forward button during swim meets. :))

Overall, this is a fun, sweet, happy watch. It's the perfect antidote after watching a few heavy dramas in a row!
