At the age of eighteen, Xia Mo mustered up the courage to confess to her unrelated brother Cuiran. Facing this girl who grew up together in a reorganized family, Cuiran, a senior, chose the cruelest rejection - not because she didn't love her, but because she loved her too much. He didn't want her to be bound by an uncertain future at her best age.
Two years later, Cui Ran, who returned from starting a business, was finally able to honor her feelings, only to find that the girl who once only cried in front of him had learned to smile gently to everyone. When he finally understands that refusing "for your own good" may be the biggest mistake in his life, can this belated spring melt the cold in Xia Mo's heart?
Concept: Love is a misplaced jet lag - when she is in full bloom in spring, he is in the cold of late spring; when he is in full bloom, she has learned to resist the cold alone. The meaning of growth may be to still choose to bloom for each other in the missed season.
