School-Friendship JMovies

Hello, I am new here. I hope I post this post on the right board.

It has been years since I stopped watching J Movie and kinda want to get into it again. I want something as the title says, J Movies that centers around friendship at school. Something like Ao to Shiro de Mizuiro  or Swing Girls. I really like to see "not lover but more than friend" relationship in J Movie. 

Though I am new, I've almost done updating my J Movie list so you could check it beforehand if you want.
Thanks in advance

• Tori Girl
• Kids on the Slope
• Linda Linda Linda
• Water boys
• Beck

I second Linda Linda Linda. Other movies that I like and would heartily recommend:

• A Gentle Breeze in the Village (same director as Linda Linda Linda; kinda slow so you have to be in the mood to fully enjoy it)
• Prodigy (about the friendship between a piano prodigy of junior-high age and a young man trying to enter a music university)
• Cheer Cheer Cheer! (a bit overlong, but I love the main character played by Aragaki Yui so I personally didn't mind)
• Ping Pong (about two ping pong players who are friends and competitors)
• Robot Contest (about a lazy girl who ended up entering the robot club for extra school credit)
• Su-ki-da (another slow Japanese movie with a lot of silence and people not doing anything; a good one that requires a certain mood from the viewers)
