Shout Out Loud! (1996)

Blurb:
Nakaya, a high school sophomore and ice hockey player, has just lost his mother and ends up moving in with Shino, his long-lost father. Shino’s anime voice acting job recently ended, so he finds work on boys' love radio dramas to make ends meet. He gets paired up with the ever-cool Tenryuu and the two bond while another co-worker hits on Shino. Meanwhile, Nakaya finds out his girlfriend might be pregnant and is forced to consider dropping out of school, but pressure to get serious about ice-hockey is building up!
