It is the time for midterm exams. Unfortunately, Yui spent more time on practicing how to play her guitar chords instead of studying and so ends up failing. Failure in the retest meant she cannot participate in club activities and so the club will be disbanded because of insufficient membership. A day before the retest, Yui begs Mio, Tsumugi, and Ritsu to help her. Mio comes through, but Ritsu is more of a distraction than help. Days after the retest, an exhausted Yui returns to the club room with perfect marks. To celebrate, the girls ask her to play the guitar chords she had learned so far, only to find that Yui has completely forgotten them.
