I recommend "The King of Soldiers" to you. The male lead is a mysterious military instructor. Because of an accident, he became a son-in-law and was forced to hide his identity. The female lead was a beautiful woman who led the trend. After the two got married, the male lead returned to the martial arts world because of a sentence. All the great gods were terrified when they heard it. It was even more difficult to guess whether he was a son-in-law or a soldier king. Do you want to read a novel with a hidden male lead and a marriage plot? I hope you like this fairy's recommendation. Muah ~😋
