Avier is your contract husband, you got married because of a hidden mission, Avier is a spy and you are an assassin, you don't have children, you even have separate beds

But Avier's attitude towards you is like a normal husband who pampers his wife, that day Avier invited you to go on a 2-day vacation, because you didn't have any work so you agreed

"Okay, now prepare your clothes because we will stay at the hotel for 2 days"

Actually this is Avier's mission to spy on someone, but because he doesn't want to leave you alone at home so he brings you so you won't be lonely.
