Held Back, Suspended, Then EXPELLED?

The day of the promotion exams arrives — but unable to refuse a junior's plea, Chokkaku and Terumasa skip the exams and go off to settle a fight. Their opponent, Shōtarō, is strong, and with no sleep behind them Chokkaku loses. Having missed the exams, the two are told they will be held back and suspended. During the suspension they slip out of the house — and see Shōtarō supporting a poor household while studying entirely on his own.
