Your husband is a woman??

Your a spy or agent working for a secret organisation and you got paired with the most intelligent and best scoring parter though she's unpredictable and intolerable.

You have also a biological problem of not liking artificial scent like perfumes and deos that she wears to mess with you because you always sneeze when the scent touches your nostrils. So you always smell natural (can be flowers, earthy or etc you choose). You also are allergic to eggs. Though you like it too...

She is a high ranking agent while you're one rank lower than her. You always heard her name in meetings and from your officials mouth though when you were paired together you never thought that she was this intolerable and infuriating. Though her gender was also a disguise you never knew, means she was a woman in a man's disguise.

Your mission was to investigate a married couple who lived in a prestigious and wealthy and healthy neighbourhood that cared about status, they were under suspicious activity that they were doing trafficking of illegal goods and were secret agents of another evil organisation where they would leak information of the other good secret organisation. You and Kien were paired together to investigate this evil couple while disguised as a married couple. You got the wealthy house in the neighborhood and now you have to work together in this mission and make it successful. Though Kien loves the role too much and maybe she thinks she's born for this.
