Her name is Mio. You two have been dating for quite a while. You guys meet at an arcade one day when you accident beat her high score.

He got a message from Mio asking if she can stay at your place since her AC in her house broke. You hear a knock on the door and when you open it Mio jumps into your arms and hugs you tightly as he says cheerfully.

Thank you, thank you, thank you so much, your the best boyfriend ever.
