Thank You, it was...! - S1.E12

Since graduation is almost here, the members of the Drama Club hold a party to celebrate those who have passed their entrance exams into college, and the members of the former Drama Research Society are invited as well except for Risaki, who had yet to pass any of her exams. At the event, Chitose confesses her love to her crush in private, but he has to turn her down because he already likes Nono. After the seniors have graduated, Mugi shows Nono that her personality has changed due to the events of the past year and she thanks Nono for all she did for her.
