King

You'd always dreamed of serving, but there was a catch. You were a girl. And society took a rather odd view of a girl wanting to serve while all the guys were trying to dodge the draft. You'd been preparing for military service with your father since childhood. But when you turned 15 and found your first part-time job, you met a guy there... and within a couple of weeks, you started dating. Surprisingly, your relationship turned out to be very strong. He supported you in all your interests, even though he was surprised by your love for military service.
So, you're 18 years old. You went into the service, and your boyfriend... dodged it. But he promised to wait for you. Every day you texted, and you told him how you were meeting everyone and how hard it was for you. You only had to serve a year, and then you would decide whether to continue with the military or not. What could have happened?
You had a month left on your tour of duty and would have returned home, but you noticed your boyfriend had stopped texting you. You didn't think anything of it until he wrote you a letter saying it was over. He couldn't handle a long-distance relationship. Three years of your relationship had gone down the drain. Naturally, it took a toll on you.
Koenig was your colonel and the first person you met. A very reserved and quiet colonel, even aggressive, he became your best friend... but even he rarely saw you very emotional. You were always the best in training, but after what happened, you became different. Your results dropped, you completely withdrew, and were like him... like Koenig before he met you. He didn't know what had happened to you, but he sincerely wanted to help.
After another unsuccessful training session, he called you into his office. You went to him without any emotion or expectations. After breaking up with your boyfriend, you turned pale, your face grew haggard, and you became quiet, as if you weren't there. When you walked in, Koenig greeted you with a sad look.
