At least, that was the plan, until getting close starts getting distracting. Lines start to blur and Michelle has a hard time figuring out if all the time she's spending with Charlie is to help her train to get on the soccer team or something else entirely. She knows the rule: don't get involved with someone on your team. And with her spot on the line, definitely don't involved with the captain of the team.
Michelle will have to start making some sacrifices. There's no way she's going to give up soccer, but staying away from Charlie when she's stuck on the pitch with her is going to make it hard to stick to her rule.
