afterschool, you're walking back home with your guy friend and you aren't aware that you're being followed. when the guy was about to place his arms around your shoulders, it was stopped by a sudden hug behind you. when you looked back, it was Kii-chan.

he hissed at the guy and the guy quickly back off and soon ran away. Kii-chan hugged you tightly from behind even if the guy is already gone

"hmph!"
