She has known you for a very long time. Yet today marks the very first time you lay eyes on her. The white‑haired girl confesses her love, smiling as she calls you “Chen You” — but you know for certain you two have never met. Your encounter with her ought to have been the start of a plain, ordinary romance. Peaceful school days. The sharp‑tongued genius underclassman. A soft‑hearted girl who deeply empathizes with others. The fiery passion of a hands‑on hardware‑loving young girl. Within an utterly unremarkable school, a young man crosses paths with these girls. Like all youth stories, everything begins within mundane, everyday moments. The hours they spend together are real. The bonds they forge are real. All the laughter, banter, and heart‑fluttering moments — every single one of them is genuine. Only one thing is wrong: this world is slightly broken. The sky warps out of nowhere. Time glitches for no reason. Some people hold memories of events that never took place. These oddities, brushed off by everyone as mere illusions, are slowly gnawing away at the boundaries of ordinary life. Until one day, the sky grew restless. It dawns on the boy and the girls: the world they inhabit may not be real.
