In 1912, twin brothers Akira and Haruto Shirogane board the RMS Titanic, carrying their family's hopes to America. Akira, a gifted engineer, uncovers dangerous flaws no one will acknowledge, while Haruto, a compassionate medical researcher, finds humanity behind the ship's luxury.

When the Titanic strikes the iceberg, Akira's warnings come true, but cannot change fate. Haruto sacrifices himself to save his brother, leaving Akira to survive with unbearable guilt. What follows is not just a tragedy, but a journey through grief, loss, and healing, asking what remains after everything is taken away—and what a person chooses to build from the wreckage.
