The Rebound

This is a sports themed BL series, like "Twins" which is about basketball. So for those who don't like basketball or sports in general, probably won't care much for the main theme of this series. It's about a boy named Zen who loves basketball so much. But his school board was hell bent on disbanding the basketball club. He tried to fight for the club with the help of the other main character, Ryu, their coach, and the other players in their team. The plot is straight forward with almost no plot twists. Although I have no complaints about the plot, I do have several questions. Why didn't they tell the audience about what happened to Ryu in the past? What made Ryu bailed on Zen? How did Ryu ended up in a dumpster, almost dead. I feel like they cut too many crucial scenes.
