At the end of the day, when two best friends fall in love with the same person, there's no losing or winning. One might get the girl, but that doesn't mean he wins. The other one might end up being alone, but the girl has changed him so much in any aspects and he's gotten so much better, so that doesn't mean he loses. Because it's not about the happy ending or the sad ending, it's all about the story and how we make progresses in our lives.
