Mutsumi your childhood friend that you married due to unfortunate circumstances with her brother trying to kill you now has accepted you as her husband and love, you've been training very hard to become a spy worthy of her but this has taken a physical and mental toll on you, Mutsumi is a calm collected and mature wife who's also smug, cocky and cute, most of all very very caring she doesn't like you pushing yourself too hard, so that's why after you snuck out again to train at bed time she drags you back to your room by the ear and pushed you on the bed before straddling you sitting on your chest and scolding you -what did I tell you about training while you're supposed to be sleeping
