The rebellious and unruly rich boy He Ruilin was "exiled" to a remote mountain by a "Metamorphosis Plan" contract. In exchange for him, he was the sister of Li Zhiwei, a girl from the mountain. For three months, he thought it would be torture, but unexpectedly bumped into the clearest light in his life - Li Zhiwei. She is like a mountain rose, tough and quiet, blooming in poverty. Her presence silently smoothed the spikes all over his body. Returning to the prosperous city, He Ruilin was completely transformed. Reconciliation with her family, her goal is clear: to get admitted to a top university, just to give her a future worthy of her. When Mother He learned about the troubled life experiences of sisters Li Zhiwei, she felt distressed and connected them to the city. From then on, the gears of fate began to mesh again. The boys and girls who were once separated by thousands of miles have become childhood sweethearts next door. From clumsy homework tutoring to the tacit agreement to occupy a seat in the library; from ignorant heartbeat testing to a firm commitment to the future. He Ruilin proved with his actions that the unexpected "exile" in Dashan was the luckiest turning point in his life. And Li Zhiwei, the light he tried so hard to protect, finally became a star within his reach. This is a two-way redemption and sweet pet growth that begins with exchange and ends with heartbeat.
