Echoes Through The Dark (A Haikyuu! Miya Twins Fanfiction: Book 2)

After an intense practice, Atsumu Miya's drive home turns into a nightmare when a catastrophic tunnel collapse traps him in his wrecked car. With crushed legs pinned under the dashboard and metal embedded in his chest, Atsumu faces a desperate fight for survival-physically and mentally-deep underground, isolated and fading fast.

Meanwhile, Osamu Miya, still healing from his own near-death experience, receives Atsumu's sporadic calls. Though helpless to reach him, Osamu becomes Atsumu's lifeline, offering strength, comfort, and hope through every trembling word over the phone.

For 15 harrowing days, trapped and fading, Atsumu clings to Osamu's voice-until rescue arrives, but the road ahead is just beginning.
