At the end of summer, Lin Weiman and Su Yi accidentally looked at each other on the day of registration as freshmen. A club recruitment flyer became their ticket to love, starting an innocent and passionate campus love song. They were preparing for exams in the library together and watching the sunset on the playground, which was sweet and beautiful.
After graduation, not long after the stable life, Su Yi's colleague Lin Jiaran showed up and she took the initiative to approach Su Yi. Su Yi didn't care at first, but the pressure of work made him gradually ignore Lin Weiman's feelings. Lin Jiaran took the opportunity to provoke constant conflicts between the two, and finally parted ways on a cold winter night. After losing Lin Weiman, Su Yi was shocked to realize that he had lost the most precious thing.
In the depth of winter, Su Yi began a long road to recovery with a letter of apology full of regret. He tried to make up for his past mistakes and tried to re-enter Lin Weiman's world. A thrilling "chasing his wife in the crematorium" began. Whether the former love can be reunited is unknown...
