I recommend the modern romance novel "Wife, please stand at attention". During the military training, the female protagonist was treated like a cow by the male protagonist. Later, she accidentally discovered that the male protagonist was her neighbor and even became her military training instructor. The male lead was a cold and black-bellied captain of an elite team. He was very strict with his training team members and was ruthless on the training ground, but when he returned home, he was in charge of everything. The female protagonist was disturbed by the male protagonist when she was eating with her male classmate. She wanted to escape but was angered, resulting in the signing of the marriage certificate. I hope you like this fairy's recommendation. Muah ~😗
