The Gamble of Unexpectedness

A typical, old bet just became serious. Mark never expected this himself. He made a bet with his friend, Ben, to see who can become a better friend to the new student, Crystal, in their class. The loser had to admit that he had a crush on Crystal.

As the weeks of education and school stuff went by, Mark eventually became close friends with Crystal. They would eat lunch at the canteen, help with each others assignments, maybe even sneak in a couple of answers to a test. But Mark thought that it was not about the bet anymore. He truly meant it. He didn't care anymore if he would win or lose.

Then, just as when things were getting better with them, Ben admitted having a crush on Crystal. Ben could not hold it in unlike Mark, so he spilled the beans about Crystal. Crystal, on the other hand, did not like Ben that much. In fact, She considers that, not knowing about the bet, Mark is a better friend than Ben.

Would it be Mark x Crystal or would Crystal still give Ben a chance? Or is there another side to the story?
