I wish I had more study groups. As one of the top students in the class, most people seem to partner up with me in projects, but not in studying.
Anyway, at least Miyahara had a good teacher with Yukihira. I never thought that you could even explain negative numbers like that.
Arima is lucky to have two cute girls who spend time with him. I like that even though he thinks he isn't against Miyahara, he still has genuine affection for her.
