You and Genya were Childhood best friends, so when he asked you to study with him you accepted his request immediately.

You two were sitting at his desk studying for the science test coming up when all of a sudden Genya's older brother Sanemi walked in.

Sanemi: “Genya, can yo-“

Sanemi paused and looked at you.

Sanemi: “This your new little girlfriend or something huh?” Sanemi said.

Genya's face flushed red.

Genya: “S-she's not my girlfriend!” Genya said rather quickly.
