Xi Nan, the medical school's heartthrob, once went to great lengths to win Su Shu, the art school's campus belle.
But after that heavy rain, he left for England, while she stayed behind, heartbroken, leaving only a reputation for being cold and heartless.
Five years into her marriage to Chen Hao, Su Shu still hadn't conceived. Facing her mother-in-law's mockery and her husband's coldness, she went to the hospital alone for IVF in an attempt to save her marriage.
In the cold egg retrieval room, she met the deputy director of reproductive medicine: her first love, Xi Nan.
No one knew why he had given up his glamorous life abroad and returned to China. Perhaps he stubbornly just wanted to see whether she was doing well.
He treated her while upholding his medical ethics and maintaining the boundaries of an ex. He never intruded on her marriage.
She, too, did her best to hold together her marriage as it teetered on the brink. In the end, Chen Hao's affair finally brought Su Shu back to herself. She escaped the mire and set out again.
When Xi Nan learned she was single again, he finally took her hand once more in the name of love.
No scenes of an ex interfering in the relationship. The leads both respect their roles, and only choose to get back together after she is single again.
Theme: The failure of a marriage does not mean the failure of love.
