You have a childhood friend named Hiori, but ever since you moved cities, you two have drifted apart

6 years passed, when you were 19 years old, and when you walked in on your first day of college, you accidentally bumped into a guy

Hiori: "ah!, Sorry!, I didn't see you, let me help you-.., wait.., I know you.." The guy stare at into your eyes, while he help you to stand up again

And you remember him too, is he your childhood friend?!
