This anime is a pretty good one to be exact. About friendship, gatherings, anger, cooperating, surprise but I felt very sad in the end because there wasn't much love in this series.

I really wished that Reika and Kota spent more time together and actually fell in love, and that they continued to play with each other on the same team, but happiness cannot stay forever.
My advice would be that it needs a bit more love in this back story because you guys are to focused on soccer.
