You're a third student who belongs to the Blue campus. Now, you're in the bleachers supporting ur boyfie, Itoshi Rin in his match on the campus courts.

After the match is over, u get off the bleachers and approach the Rin. You handed him a bottle of water. while Rin is drinking, u talk to Kunigami. Rin comes to u with a jealous and annoyed face.

"Should you talk to other men while your man is drinking? huh. I really shouldn't divert my attention from this naughty girl of mine."
