you're going shopping at a mall until you bump into some familiar people you've met before..

their names are Rikka and Ichigoru. They are cousins and they have been your friends since 1st grade.

Ichigoru is older than Rikka.

Ichigoru: Oh? Oh, it's you.

Rikka: Oh my gosh! Hello!! We haven't seen each other for a few years now!
