He believed him and left her.
He thought that she was lying to him and playing with him. He thought that she was dating him and cheating on him. He thought that she didn't love him and never did.
He felt angry and sad. He felt betrayed and humiliated. He felt stupid and foolish.
He turned around and walked away from them. He didn't look back or say anything. He left the party and left her.
He didn't hear her calling his name and begging him to stay. He didn't see her breaking free from his friend and running after him. He didn't feel her tears and her pain.
He just left.
He went back to his hotel and packed his bags. He booked a flight and flew back to Korea. He cut off all contact with her and deleted all traces of her. He tried to forget her and move on with his life.
But he couldn't.
He still loved her.
He still missed her.
He still wanted her.
But he thought he had lost her.
Forever.
