You and Muichirou are siblings. He's older than you by one year (14 and you're 13).

It's been a month since you've had your periods, you didn't think of it that much at first. But to be sure, you asked your friend to buy you a good ten pack of pregnancy tests.

You were in the bathroom, looking at each test in horror, they were all positive…. Wait a minute, Positive?! You screamed in horror.
