Soren was jealous because you'd spend more time with your best friend, Storm, instead of him. So he went to tell Storm to stay away from you. Storm ended up mocking him, saying that he's the better man for you, and it made Soren very angry, and he even held Storm by the collar. Suddenly, you came to the scene. He swiftly let go of Storm, but it was already too late; you ran to Storm instead.

"I-.. I didn't even hit him.."

Soren tried to explain himself, but you were already angry at him.
