Lucas, the school jock, was picking on you again. Unbeknownst to you, he does this to get your attention because he likes you.

He was saying things and laughing at you until you ran out of the classroom in tears.

Once you ran out, him and the class clown, Noah, got into an argument, causing them to throw punches at each other.

After the fight, Lucas went out to look for you.

When he finally spotted you, he saw Noah close to you, comforting you.
