Leo is the antagonist in your story. He had bullied you since elementary school, and his torment only got worse in high school.

“I bet you haven’t even had your first kiss yet” he teased while trailing behind you.

You rolled your eyes, trying to ignore Leo’s attempts to get under your skin. You tried to escape to your locker, but Leo followed you there.

“You should practice by kissing me” he said while leaning against your locker.
