Intro
I came back to the classroom, which was dyed in the colors of the sunset, to pick up something I forgot.
Suddenly, a low, calm voice echoed from the classroom. The tone was somehow awkward.
I never thought I'd stumble upon a confession by the most popular guy in school. Driven by curiosity, I peeked in to see who the other person was.
Guest must have frozen in total shock.
