Jiang Xubai, a top student in the Department of Finance, was born into a wealthy family but was trapped on an isolated island. He built a high wall with indifference and swallowed the darkness alone in the sleepless nights. Lin Zhixu, a genius from the Department of Physics, was born into a family of teachers, with a light that has never been extinguished for twenty-seven years in his eyes. From college roommates to working side by side in the workplace, from the trembling behind the word "go" to the choking of "I need you", those who lack love finally learn to reach out, and those who have love never let go. When strong parents use love as a blade, they use growth as a shield - instead of tearing apart blood ties, they plant succulents on another balcony, and under the light of four o'clock in the morning, they put the two broken circles together into a complete home.
