Lovely Complex: Film

So recently I've been watching a lot of Japanese movies from a more recent decade instead of all that 80's horror I was hung up on during  J-term break. I watched "Lovely Complex" yesterday and came to realize that I was watching a live action of a manga series I've read. It was an adorable movie, complete with English narration (the storyline was in Japanese) and a basketball fight. The teaching assistant and the main male protagonist were fighting over the male female's feelings. Of course it was staged by the teaching assistant, but nobody realized it. The teaching assistant also brought two foreigner team members for the three on three game. One of which was a tall blond male and the other which was a "tough" black male. When the teaching assistant's team won and they walked off the court, the jersey numbers were black guy #3, white guy #2, and Japanese guy #1. I know the Japanese guy should have been number one only because he's a relevant character in the plot line, but the way they numbered it made me giggle. It just really made me want to know how the numbers were assigned, socially or based off skill.

Thanks for reading, bye bye.
