When Ding Qian and Xia Lu met, he was fifteen and she was nine. According to seniority, she should call him uncle. Unexpectedly, the little niece who is not amazing in appearance seems to have the "super power" of hearing people's hearts. A secret hidden deep in time. A teenage love story that walks the line between sweet and bizarre. A most wonderful transformation. The coolest secret book on chasing love. Where should this unethical love go in the eyes of the world? Can you hear my heart? I would like to write this book to commemorate our unique youth and frivolity in the time mottled by love.
