In order to inherit the cafe left by her mother, Lin Youyou, a freshman in law school, made an agreement with her father: she must get married before graduating from college. When she was desperate, she reached a secret agreement with the campus boyfriend and second-year law student Lu Xingchen - a two-year contract marriage, each getting what he wanted.
Unexpectedly, this perfect senior who is known throughout the school as the "iceberg academic master" is actually a loving husband who will boil brown sugar water for her, stay up with her to review all night, and even go all over the Internet for her. When the contract expired, both of them found that their hearts moved beyond the agreement.
