I am... shocked. Guys, this is a perfect example of a toxic relationship, a Stockholm syndrome if I have ever seen one.
What is the point of this one-shot? It is disgusting, a caricature of real relationships. A guy who calls his girlfriend a "dog", who cheats on her, humiliates her, mistreats her and all is well 'cause he gave her, in the end, a pendant? Are you serious? Throw this pendant in the ocean Titanic-style, dump his sorry ass, get some self-esteem and live your life happily. Please, to the young and impressionable girls out there, if your guy treats you like the main protagonist, run the hell away, celebrity or not. You are valuable, you are amazing and you deserve to be treated respectfully. The best happy end of this story would be the guy coming to an empty apartment.
