I loved this anime so much and reki.... I kinda relate to him. He taught his friend how to skate but in the end his friend turned out to be more brilliant so he was jealous.... I have the same experience but I am also in good relations with those people..... I am glad reki understood that too and skated because it is fun not to compete... I thing we must learn from real life and from this anime that is never compete with others, try to challenge yourself
