Junta Hayami

The "childhood friend" that Riri set up for Anzu. Anzu originally believed him to be a random hot guy brainwashed by Riri, but it is later revealed that he is in fact a childhood friend of Anzu.

He had picked up baseball and changed himself after overhearing Anzu say that she would like to date an "athletic guy who can beat the boss."

Anzu is aware of his feelings for her, and acts oblivious to hide it from him.
