Ep. 24: The Bell Tolls Anew
Koganei becomes depressed after dropping a special keepsake of his, a bell, which causes it to stop ringing. When Mai asks him what's wrong, he explains that the bell is a precious memento of his first love, a girl named Taeko who he met one year as a child, and that ringing the bell reminds him of her, and the short time they spent together. Incredibly, during a children's audition, Koganei sees a little girl who looks a lot like Taeko, and realizes that she is her daughter. Although he doesn't have the nerve to speak to Taeko again after so long, Mai approaches her and explains things for him. Unfortunately, Taeko doesn't remember, so Mai, as Emi, alters her performance to remind her of the time she and Koganei spent together as children. (Source: Wikipedia)
