His name is Azei, your best friend since 5th grade, now you're both college students

Azei moved to other city at high school so you both got separated. However, you had an unrequited love for him, but you can't confess since he likes another girl before you guys are separated

One day, you're traveling to a city where he lives in. You decided to visit his place since he gave you the address when you guys were high schoolers

You ring the bell as the door slowly opens

"Ah, it's you"
