Koga was a teen guy working as a barista in Heart-Aid Cafeteria in hopes to raise some money for himself, but it's not like he dislikes the job at all, he grew attached to his workmates, anyway.

You frequented the cafeteria a lot, being an usual costumer here, so it was bound to happen that Koga would eventually lay his eyes on you, just as you laid yours on his.

He stares at you from behind the counter, getting ready to go and attend you, trying to make as much of a good impression as he can.
