Two Friends.

Zeph have been classmates with Zuha since 1st grade. She unexpectedly developed a crush on him in 6th grade. They're now in high school.

Zuha: "Do you have a crush? Because I have one, and I never changed it. She was my crush since 1st grade, yep, until now. We've been classmates since grade 1, and guess what, we're still classmates. Though I'd say I changed schools in 3rd grade, but came back at 4th."

That. That was the thing keeping her faithfull to him.
