Lin Zhixia is a "good girl" in the eyes of outsiders, with excellent grades and a quiet personality. But the inner desire is to break through the constraints, to have a wild imagination and a sensitive and delicate heart. She has always been secretly in love with the "little sun" who protected her since childhood - Lu Xingchen.
He seems to be an unruly "problem boy" who loves basketball and street culture. His grades are low, but he values love and justice. Only when dealing with Lin Zhixia, would she put away all her edges and show incomparable patience and gentleness. His dream is to become a professional basketball player.
It wasn't always smooth sailing for them, but in the end, their youthful crush became a two-way affair.
Concept: The love between childhood sweethearts is not always smooth sailing.
