Characters/acting:
The characters don't give me butterflies and the acting is dead. Seto's lines are unbelievably boring. All my expectations just went drastically downhill, because I was looking forward to the scene where the couple has a conversation before the basketball match, after they meet officially for the first time. (Oh, the butterflies in the Chinese version!) It was just so disappointing. The characters are less manly/feminine and that shift made me so confused. There should be a fine line between each characters, but non of them have a basic and distinctive characteristic that belong to a specific character. All of them are just one blur. All of them act the same and the dialogue is boring. I'm not putting all of the blame on the actors/actresses but the director, acting teachers and the scriptwriter could've done a better job in guidance.

Everything else/comparing to the Chinese versions:
The animation/greenscreen sucks. I've seen what Japan can do, but I think this production just has low budget. All of the episodes are less than half an hour long, so everything is rushed, speed up and non of the details from the original plot is shown. I understand that Japan's tv slot time is different, but this was just irritating. It's dissatisfying to watch compared to its Chinese drama counterpart. It's kind of annoying and frustrating because it had so much potential. Even the Chinese movie version was better smh. I don't recommend watching this unless you're extremely bored.
