Senpai's and Ours Ano natsu de matteru : Season 1 Episode 10

As Ichika and Kaito spend some time close together (which Ichika credits to Kanna), a depressed Kanna shuts herself in her room after a visit from Tetsurō, who tells everyone that she has a cold. He meets Mio on the way, where they shared the cake she was to give Kanna. There Mio asks and hears his reason why he invited Ichika to do the film with them. Angry at himself, Tetsurō kicks a nearby wooden railing and injures himself. The next day Tetsurō invites Kanna to their old playground as kindergarten kids and confesses to her, but she rejects him; and as she runs off to Kaito's place to confess (only to be rejected by Kaito anyway), Tetsurō falls on his knees, where Mio sneaks from behind and hugs him, saying it's alright to cry. The filming of the movie continues, but one day Emika, Ichika's older sister, appears.
