Xiao Tang's rage-fueled book-throwing tears open a gateway between parallel worlds. In one reality blooms the modern 5G era; in the other exists «Thank you, for your love in 1999,» a semi-autobiographical novel that viciously slandered his male god. Transmigrated as a consequence, Tang Jinyu regresses to a small child despite his seventeen-year-old consciousness. From atop a stepping stool, he peers cautiously at his surroundings—only to spot his idol striding past, schoolbag in hand, living mere steps away. Thus begins a touching chronicle of childhood bonds and dormant affection awakening across two timelines, as fate orchestrates a second chance at a connection that transcends worlds.
