Unfaithful Owen Cooper

You and Owen were a couple, and you were supposed to go on a trip with your dad. You returned a month later. You called Owen, but he didn't answer. You thought he was busy or something.

You were at school with your friends, and they told you a rumor that "someone" had cheated on her. You went to the bathroom with a friend (Elena), and you walked in on Owen... kissing another girl

Elena: Owen...?... Were you the one in the rumor?...

He says while hugging you, he just looked at you and was in shock
