While this is not my favourite BL of all time, it is one of the go-to BLs whenever I need a short pick-me-up.
The series and the drama are identical, there are just a few scenes swapped around where the episodes end / start, probably for narrative reasons.

What I liked:
* They chose a story line that is adequate for the length of the series. Anything more complicated, and it might have become frustrating (again).
* The series is focused on the two main leads, which are supported by only a few other characters, which also fits the drama's length. I loved all of them, the coach was like an exasperated but loving uncle, the friend insightful, the two loan sharks hilariously cute.
* They did almost everything to keep the story light-hearted, from the sometimes cheesy dialogue to the upbeat music.
* The story, though straightforward, shows quite a bit of character development for BOTH main characters.

What I did not like:
* To keep it consistently light-hearted, I would have liked if the scene with the loan sharks' boss could have been less violent -- I'm sure there was another way to put pressure on SangHa than to beat him up.

Overall, a sweet and short drama.
