The main storyline is that Xia Xinyuan adopted Xia Yiyuan. When he grew up, Xia Xinyuan fell in love with Xia Xinyuan, but because Xia Xinyuan thought that he was his younger brother and could not be together, he rejected Xia Xinyuan. In fact, Xia Xinyuan also liked him, but she didn't dare to say it. He said, "We are not related by blood, so we can be together."
