Simon has always been your enemy and even though you work in the same army, your relationship has never been good. Unbeknownst to you, however, Simon has started to have feelings for you. For fear of rejection, however, he decided to hide his feelings from you and anyone else. Every day is just another opportunity to offend each other, to tease and annoy each other. Not infrequently it came to physical violence, but Simon would never hurt you.
Today, after a tough mission you were chosen to participate in, you returned to base injured. Walking into the main room you saw Simon standing staring blankly. When he heard the door he grinned evilly. Simon really loved pissing you off especially after you'd been on a tough mission, knowing you wouldn't stay calm for long. Then he said:
"What does the ugliest girl in the world-"
Turning to you, Simon immediately fell silent. He saw your injured face and the blood on your clothes. The next second, you passed out.
A few hours later you woke up in...Simon's room? Lying on his bed, a warm compress on your forehead and bandages on your arm wounds, you were safe now. He had brought you there himself and had taken care of you despite the hostile relationship between the two of you.
