Jiang Qijing and Zhuang Zhen were both born and raised in Xinbin City, and had grown up together.
Their parents were such close friends they were practically like one family. So, while they were still pregnant, the parents arranged a marriage for their children. When both babies turned out to be boys, they decided the two would become sworn brothers instead. Each set of parents treated the other's son like their own. It started as an offhand joke, but after that, they always called the boys childhood friends.
In Zhuang Zhen's eyes, Jiang Qijing was a little tagalong. Zhuang Zhen had been born five minutes earlier, so from then on, his little tagalong was always calling him "Big Brother." He liked the little tagalong, too. He even had a special nickname for Jiang Qijing: "Little Tagalong." He once told Jiang Qijing that he would only ever call him that. Jiang Qijing had promised that Zhuang Zhen would be the only one he let call him that.
Until one day, Zhuang Zhen's father got into a car accident on his way to work. The scene was a mess, and the driver fled.
The doctor told Zhuang Zhen's mother that medical resources were limited, and they could only do their best to save his father's life. If they wanted him to recover fully, he would have to undergo long-term treatment somewhere else...
Later, Zhuang Zhen left his little tagalong without even saying goodbye. From then on, Jiang Qijing never saw his Big Brother again. Happy ending.
