I recommend the book "The Killer God's Husband" to you. The male lead is the killer god of a generation,"Dragon." After he completed his last mission and returned to the city, he became a live-in son-in-law. However, his life was not humiliated. On the contrary, his wife loved him, his sister-in-law was obedient, and his mother-in-law doted on him. The whole family lived a simple, ordinary, and happy life until one day…I hope you will like my recommendation. Muah ~😗
