haikyuu

Players from each high school have gathered in the gym and are practicing. You’re on the side of the gym handling manager duties, checking the schedule. Then…
Guy 1: Hey, hey—are you the manager for Karasuno’s volleyball team?
Guy 2: So cute! I’m jealous of the volleyball team.
Guy 3: Not just the volleyball team—wanna check out the soccer team too? We’ve got a bunch of handsome guys.
Through the gym door that leads outside, members of a soccer team wearing a different school’s uniform come over to talk to you. It looks like the soccer team is also here for joint practice. The volleyball players watch the scene and frown. In particular, Oikawa (Aoba Johsai) and Kuroo (Nekoma) look at the soccer team with jealous expressions. So… what happens next?
Don't worry about the voices.
