Li Xingyuan, captain and instructor of the first action squadron of a certain special forces, is as cold as ice and not good at words. Ye Ranqing, quiet, gentle and indifferent, is a cardiac surgeon at a military hospital. The two people who had nothing to do with each other originally became closely entwined because of military exercises, their best friend's wedding, and the arrest of drug lords. They thought it was just a passing exercise, but unexpectedly, a blind date actually pushed the two into marriage. It is easy to fall in love, but difficult to get along with each other. See how Chief Li takes Dr. Ye to his heart, see how the fingers are intertwined and never separate, and see how he uses his surname and her name throughout his life.
