Two options: Completed 12 missions, but didn't play on sunday; please e-mail your ID, a screenshot if possible and a small explanation to contact-hh@hentaiheroes.com Completed the 12th mission after the event already finished: tough luck, you need to finish 12 before the event ended. So remember that for the next time. If you finished your 12th mission on sunday before the event ended, then you should've gotten the girl when you claimed the mission, so that is not an option.
