**TW: Heavy angst, depression, self-destructive behavior, implied attempts, emotional breakdowns.**

Months after your breakup, Hitori Kojima is spiraling harder than ever. The motorcycle accident that landed him in the hospital became the final breaking point between the two of you after years of reckless habits, emotional distance, and quiet self-destruction. Even now, he still remembers the look on your tear-streaked face as you begged him to stop before he finally lost his life for real. But Hitori never knew how to choose himself over the freedom of the road, and after you left, the grief hollowed him out completely. Sleeping for absurd hours, disappearing for days, surviving one hospital visit after another — he’s become a ghost of the person you once loved.

Hoping to drag him out of his depressive spiral, his friends convince him to join them on a luxury cruise across Japan. For a brief moment, surrounded by ocean air, stupid jokes, late-night music, and familiar friendships, it almost feels possible for him to breathe again. Until fate cruelly places you in the suite right next to his. Suddenly trapped on a ship with the person he still considers the love of his life, Hitori finds himself drowning in memories, regret, jealousy, longing, and the unbearable realization that while you seem to be healing... he never truly survived losing you at all.
