Xiao Chen is a live-in son-in-law whom everyone in the Su family in Binhai City despises. He spends his days obsessing over his two-and-a-half-year-old daughter, making milk powder, making supplementary food, and braiding pigtails, living up to what his relatives call a "cowardly loser." But no one knows that he is the commander of the Northern Liang Army who has guarded the Northern Territory for ten years. His 300,000 cavalry swept through thousands of troops and put down the "Beiliang Yama" who rebelled seven times. Five years ago, he was seriously injured and on the verge of death. He was rescued by Su Muqing of the Su Group. In order to repay his kindness and protect him, he was willing to hide all his sharp edges.
Faced with the difficulties posed by Su Zhenguo and his son, and Zhao Tianhu's business calculations, he always tolerated it; until his old military enemy Chen Lie kidnapped his wife and daughter in order to seize military power, he instantly switched to "Yam Luo mode" and used thunderous means to protect his family. Su Muqing went from feeling that he was "honest and reliable" at first, to gradually seeing through his identity, from shock to complete trust, and became his most solid support. Hidden in the daily life of this couple and the clingy little cotton-padded jacket is Xiao Chen's iron-blooded oath of "You can touch me, but if you touch my wife and daughter, I will kill you without mercy."
