Being childhood friends has been a ten-year-long one-way street. Shen He stood by Sui Yu's side, watching him fall in love time and time again, hiding his secret behind every casual, side-by-side walk. Until a transfer student arrived like an unexpected ray of light, slowly pulling Shen He out of the orbit that revolved around Sui Yu. And at this moment, Sui Yu, who had never once looked back at him, felt for the very first time—that something had spiraled out of control. Shen He and Sui Yu have lived next door to each other since childhood, as close as two plants with intertwined roots, coexisting yet remaining silent in their own ways. Sui Yu is dazzling and radiant, while Shen He is quiet and introverted, like a planet orbiting its star.
