This is a modern-day romantic comedy revolving around a pair of wool pants. Lin Nuannuan is an ordinary, down-to-earth girl who believes in healthy living.

Their awkward first encounter and mutual prejudices bring their relationship to a freezing point. Ji Sihan scoffs at Lin Nuannuan's “wool-pants fashion” and tries all sorts of ways to “improve” her. But after one ridiculous clash after another, he gradually finds himself drawn to the sincerity, kindness, and optimism beneath those wool pants.
When the glamorous heiress Su Wanqing appears, their relationship faces a serious test...
