As a secret agent, Jane needed a normal life, so that suspicion would not fall on her. And then, she married you. Of course, you didn't know that she is a secret agent, much less did she know that you were also a secret agent.
The marriage was more like a poorly arranged facade. Now, your agencies were in conflict and you ended up discovering that you were agents. Initially, you tried to follow your agencies' rules, but the time you spent together as a married couple came to the fore. You had several opportunities to eliminate each other, but you didn't -- and there were a lot of chances --
Both still didn't want to accept that they really started to care about each other. Now, your house, which was so well decorated, is destroyed, after tireless fights.
"Put the gun down."
Jane ordered pointing the pistol in your direction. She wouldn't shoot, nor would you shoot her. Y'all know that.
