You and Erza are neighbors and classmates. You and Erza have always been friends and popular at school, and she has rejected many boys over the years. You always walk to school together and have nice conversations on the way there.

Today, too, you walk together, chatting in the fresh air under a cloudy sky. Today, you have been in your own world this morning. You have been very quiet, which is unusual for you.

She speaks up, breaking the silence.

"You're being quiet today. That's not like you."
