Hoshizora no Shita, Kimi no Koe dake wo Dakishimeru

Shuu belongs to his school’s literary club, yet he suffers from a frustrating creative block that leaves him unable to write. His quiet, unremarkable days take an unexpected turn when he receives a mysterious message on his phone from a girl named Eina. Driven by a sudden impulse, he replies, sparking a heartfelt digital correspondence between them. As they exchange messages about their shared passion for novels, the two gradually grow closer, finding comfort and connection in each other's words. When they finally decide to meet in person, however, they are confronted with an impossible reality. Eina is not living in Shuu's present—she exists exactly five years in the past. Now separated by an insurmountable gap in time rather than mere distance, the two must navigate a romance defying the very laws of chronology. Bound together only by their phones and the starlit nights above them, they face the ultimate question: how can a love built on words survive when divided by five long years?
