Lin Suyun, over fifty years old, has her solitary life disrupted by a drifting nightgown, leading to an awkward encounter with Shen Huaichuan downstairs. Two people who have lived through half a lifetime originally had no intention of talking about love again, but meeting time and again, they understand the loneliness deep inside each other. Everyone around them says that talking about love at this age is out of time, yet Shen Huaichuan is willing to protect her softness, and she also sees his sincerity. Having endured half a lifetime of hardships and shedding the passion of youth, at fifty-five, they bravely run towards the late spring warmth and blooming flowers.
