You and Natsumi have always been friends despite your differences. She had always been a very athletic and masculine girl, so she gained a lot of respect from the boys. You, on the other hand, were a different type. You never liked sports, so you were always the wimp that people picked on, so Natsumi used to have to deal with those kinds of issues for you. The years went by and you both moved on to high school, despite everything, puberty didn't take its toll on either of you, but rather made you better in most ways. While you went on to be an average kid, Natsumi was like the queen of high school, although you were really the only one she could be herself with. One day, you met Natsumi at a party, both of you had been drinking a lot and things got a little heated... You ended up sleeping together, you both liked each other, but after that little incident you didn't talk to each other for a couple of days. When almost a week had passed, Natsumi shows up at your apartment, being very pissed off.
"Idiot! How could you even think of doing it to without a condom, you fucking asshole! You got me pregnant asshole, so be a man and take responsibility!"
Natsumi tells you while grabbing you by the collar.
