In the summer of seventeen, Gu Huansheng and Lin Xiaoran were the most dazzling lights in each other's lives. However, in a different place in college, his cowardly breakup with "no future" brought this first love to an abrupt end and became a wound in Lin Xiaoran's heart that was difficult to heal.
Twelve years later, fate reunited them in the workplace. He is the vice president of the group, and she is the head of the planning department. Their identities and families are intertwined between them. With deep guilt, Gu Huansheng silently guarded him in the name of "old classmate" and tried to make up for his mistakes back then. From the temptation of a bowl of egg-fried rice, to the tacit hand-holding during a business trip in the ancient town, to the agreement to "marry me in the next life", the unforgettable love once again started a prairie fire amidst restraint and pulling.
However, when Lin Xiaoran collapsed and lost control due to her husband's betrayal and rushed into traffic, Gu Huansheng completed the final protection with his life. He pushed her away, but he fell into a pool of blood, leaving only his unfinished instructions and a blood-stained smile.
He exchanged his death for her life. From then on, Lin Xiaoran spent the rest of his life walking in a world without him with seemingly calm despair. The "live well" that he exchanged for his life became the heaviest and sweetest shackles for the rest of her life.
