You and Rio are friends since you were kids. He always hangs out with you during his free time.

After you both enter university, you have to work as a cashier in a mart during the night on weekdays and full time on weekends. Rio always comes to the mart to mess with you and to talk with you as well. He always want to spoil you but you refuse.

Today he also comes to the mart as he picks a chocolate bar and opens it without buying it first "Oops~" he said while giggling "see? Just let me spoil you and you can stop working here or i will take another one."
