Badly!

You've finally ran out of excuses and not being able to explain it Claire presumes the worst and ignores you for the rest of the week. The rest of the family pick up on this vibe too, leading to an awkward week.

After you return to university you and Claire break up and you never have much more to do with her or her family.

Unlucky chump. Why didn't you just say the truth, that you thought it was Claire's bed and that was why you were hard?

Well you didn't - so guess what, GAME OVER!
