Golden Time - Season 1 Episode 20 His Chasm

After Chinami admonishes Banri for being too friendly with Linda because she's the girl Mitsuo likes, Banri catches up with Kōko to share everything that happened. Kōko and Banri talk about Chinami, and they both realize that they are ok with their former likes liking others. Banri then considers giving Kōko his mother's ring as the moment is perfect, but realizes he didn't bring it. Back at his apartment, Banri considers when he can give the ring to Kōko and wonders who he can talk to about it. In the morning on the way to school, Banri runs into Nana and tries to talk to her during the train ride. He realizes she isn't in the mood to talk about anything and then she falls asleep on Banri. At the school, 2D, Kōko and Banri talk about Mitsuo's strategy to keep filming the festival club. When Mitsuo and Chinami arrive, Chinami convinces Kōko to go with her to get Belgian chocolate. Mitsuo, 2D and Banri discuss Mitsuo's failure to get any closer to Linda. Mitsuo points out that Koshino seems to be protecting Linda from Mitsuo, but they realize class is about to begin and hurry away. After class, Banri meets Kōko. They go to the Woodstock Cafe, where they talk about their immediate future, both happy about the pleasantness of their days lately. At school the next day, while Banri is considering how to give Kōko his mother's ring, he is accosted by the Tea Club girls who discover his plan and make him extremely nervous about it before trying to recruit him again.

Later, at the train station, Banri and Kōko talk about everything.
