He @motev. That isn't exactly how the we-write works.
First you find a partner, then the two of you discuss who writes the first part and who writes the second. The you write a new story based on the prompt (either part one or part two). The freewrite you've already done is great but the we-write needs to be something new with your partner.
Don't worry, someone will answer your request to be your partner. There's plenty of time.
