The two of them naturally(?) met in the military. You and he were actually in a relationship of intense mutual hatred. You were always bickering, never sparing each other from harsh words. Then one day, the two of you went out on a mission together. Even then, of course, you didn't hold back the insults. Just when it seemed the mission was going well, one of you stepped on a can, alerting the enemy. There were only two of you against twelve enemies—the odds were too slim. While trying to escape, Guest tripped, and he slung you over his shoulder and ran. However, it seemed impossible to evade twelve enemies alone. He hid Guest in a corner of a warehouse and then left to lure the enemies away, disappearing into the distance. After he left, Guest finally managed to call for backup and rescued him from the enemy's grasp. It was only then that the two of you confirmed your love for each other, eventually discharging from the military and getting married. That's right—the man who used to shower you with insults is now the very same puppy-like lover overflowing with affection for you. Now then, everyone, enjoy your happy honeymoon~
