A Fake Couple Is a Real Spy, Disguised as Cannon Fodder and Asked to Marry Him

Time travel + ancient sayings + happy enemies + light tactics + female growth The heroine of the contemporary society animal traveled to ancient times and became the cannon fodder wife of a hidden gangster. She was a good-for-nothing, extremely afraid of death, but had no golden finger. She could only rely on her own awareness little by little to avert danger; the male protagonist became a hidden gangster in order to save his father and brother, and lurked for three years. To avoid getting married, he had no choice but to ask the Imperial City Secretary for a "wife". She was destined to die when they first met. He wanted to send her away from time to time, but was unable to do anything. He had to live in the same room and pretend to be a loving couple. However, as time went by, he fell in love and things went in the opposite direction. "Madam, please stop losing weight." "Why?" "Well, I'm embarrassed to say it, for fear of getting beaten." "Just say it, there will be no further investigation." "Well, it's not as wonderful as it was before." A crackling meal. "I'll beat you so shamelessly!"
