This is one of the best bl series I have seen. The actors were all very good, not only the main couple but the overall quality of the actors was very high, and the chemistry between our leads was beautiful. I also really enjoyed the story although I do believe the ending could have been extended (as I don't think there'll be a second season) or maybe there could have been a special episode about how things developed after the series finale.
It's cute, sweet, with adorable characters and great actors portraying them, the camera work is pretty good also, and the shots of them playing volleyball are very nice.

I honestly can't recommend this enough. It's just a breath of fresh air when it comes to bl romance.
