I recently watched this series for the second time and wanted to write a review, since I didn't write one before.
This series is very good, but it also focuses on more than just romantic relationships: it's mostly about following your dreams and finding a balance between your dreams and the other things and people in your life, about finding happiness in unexpected places, and about finding in yourself a light even when all hope is lost.
The story is about three different couples of sports science students, the main one being the best written in my opinion.

Thorn and Fah make a cute couple and I really liked their story. Their background as childhood friends was explored well and their relationship includes both their romantic feelings for each other and their love for basketball. I really liked the fact that basketball here is not just an aesthetic for their setting, but it's not a minor detail of their characters either: it's present throughout the entire series and a very important part of their dreams and ambitions, often functioning as a way to portray their emotional state at best. It's something I rarely see in series set in university and I really enjoyed it.
I also really liked the idea of them growing closer as they decide to be there for each other and support each other. Their balance is not always good, Thorn is often times the one left with the shorter end of the stick, but this aspect is shown very well in the series. There is quite a bit of angst for them, especially during the last few episodes, but despite it being painful it was a pretty good journey. Tae and Suar don't have groundbreaking chemistry with each other, but it worked for me.

Aii and Saen are a very cute couple together, and also the one that brings less heartache and less angst to the series. Saen's passionate and sincere courting towards Aii was just adorable, and it was also very satisfying to see Aii slowly but steadily warming up to him. I was afraid that Aii would either fall too fast or end up as one of those partners who stay grumpy and reluctand to the end of the series, but that was not the case at all. This couple also faces the long-distance relationship theme, which was handled very well in my opinion. Something I didnt' like was the fact that, while Aii's passions and dreams were thoroughly talked about, Saen was not explored as much.

Finally, Vee and Dome were the recipe-for-disaster couple. On one hand, they were kind of a let-down, because their scenes were focused almost exclusively on the growing feelings for each other and barely anything else. They are also the only couple that strays from the dreams/ambitions/love balancing struggle of the other two couples, so they felt out of place to me. What compensates all of this is their chemistry, which was undoubtedly amazing: their gazes alone said all they needed to say and it was enough to make them very interesting to watch.

The production was pretty good as well, with a good use of camera angles and interesting shots - I wasn't a huge fan of the persistent yellow tone over the entire series, but I got used to it after a couple episodes. I read that other viewers had trouble keeping up with the story because of the flashbacks and time skips, but I personally didn't have trouble understanding what was going on.
The music was, for me, the worst part. It was decent most of the time, but I really didn't like the songs and felt like they runied the moment more often than not.

I recommend watching this at least once!
