Shen Nianxi, an 18-year-old freshman in the music department, accidentally "hit" Gu Tingfeng, the campus god who suffers from apathy, during an impromptu accompaniment at the opening ceremony. He approached her in the name of a "healing contract", but he was sincerely moved by her as they got along day and night. From campus confession to resistance from wealthy families, from online violence to separation in a foreign country, from fighting side by side to wedding crisis - after four years of ups and downs, the two healed each other with the sound of the piano, resisted the world with love, and finally made a lifelong promise at the graduation ceremony. This is a story about "two-way redemption": she lets him learn to love, and he lets her dare to fly.
