Stuck Problem

In order to help Nagisa reform the drama club, her friends offer their names in order to get enough members to qualify, but they still need a teacher to advice them with the club, which leads them to ask Toshio Koumura. However, he is already meant to be the adviser for the choir club, so Nagisa goes to talk with Rie Nishina about which club Koumura should advise. The next day, Nagisa finds a threatening letter in her desk, and Youhei finds out that it was Rie’s friend Sugisaka who is behind it. After talking with Nagisa about Rie’s past, Nagisa chooses to give up on reforming the drama club, though this does not sit well with Youhei. Tomoya and Youhei go to Yukine Miyazawa to kill time during school, and Yukine gives Youhei an idea related to basketball. The next day, Youhei approaches Tomoya and Nagisa about playing in a basketball match in order to get the choir club to back down, but Tomoya continuously refuses his offer.
