[1970s setting + six-year age gap + height and build difference + voluptuous beauty + both leads are each other's only partners]
Lin Ying, a pharmaceutical industry big shot, transmigrates into the body of a chubby girl who shares her name. Her stepsister, Yang Mengdie, steals her fiancé, a civil servant.
For the bride price, they also want to marry her off to her soldier fiancé, Lu Lin, who has been missing for five years.
Lin Ying writes to Lu Lin, exposing Yang Mengdie's plan to get married and swap her out for herself, leaving him with the chubby girl as his wife.
Lu Lin returns to his hometown on leave and rescues Lin Ying when she steps in to help someone in danger. He visits her home, only to discover that the woman claiming to be his chubby fiancée is actually stunningly beautiful.
As it turns out, the man who had been missing for five years has now become a regiment commander. Her stepsister regrets it and wants to get back together with him.
But Lu Lin falls in love with Lin Ying at first sight, and his feelings only deepen when they meet again. He launches an all-out pursuit.
Everyone in the military district knows that Commander Lu has married a beautiful, delicate wife.
The once cold and fierce Commander Lu now talks about his wife every day.
He thought he'd married a pampered young lady, but who knew she'd go on to work at a pharmaceutical factory, become its director, and make a roaring success of it?
Every night, the cold-faced King of Hell, Commander Lu, pesters his wife to make a baby.
"Be good, honey. Let's have another chubby little boy!"
Lu Lin becomes more and more intrigued by this chubby girl. He finally comes back before Yang Mengdie's wedding and falls in love with Lin Ying at first sight.
By then, Lin Ying already has someone she likes. Lu Lin narrows his eyes. He will never let go of the woman he has set his sights on!
