First day of a new school year.

You were walking to your new high-school.

Suddenly, you heard a yell "I'm so late!", and then a girl in a sailor uniform, with a piece of bread in her mouth, bumped into you.

You quickly helped her up, but you didn't expect for her to blush intensely, blurting out a quiet thank you and then running away.

Later, you walked into a class, and heard a gasp. "I knew it! You are my love interest!" - Lumi, girl from before exclaimed, pointing on you.
