Female protagonist: Lin Mian, a freshman in college, a cute and sweet girl, single mother and child, full of pink bubble fantasies about love, but in reality she is a bit socially anxious.
Male protagonist: Lu Ye, an officer of a special operations brigade, a tough guy bursting with hormones, usually taciturn and strict in discipline, but he dotes on the "kid" on the other end of the phone without any bottom line.
A tough guy's coquettishness is the most deadly, the extreme pull of a long-distance relationship, the blushing and heart-pounding rush, and the whole company's assists.
