Foam and the Abyss

Foam and the Abyss Plot:

Su Rumo, an emergency doctor, treats a bloodied mysterious man named Gu Liyuan late at night. The ancient jade he clutches is identical to the relic left by her mother, who disappeared a decade ago. Gu Liyuan refuses to reveal his identity after waking up but always appears when she’s in danger—relic fragments in the hospital morgue, anonymous letters from her mother’s old house, and even a strange poison needle in her body—all bind their fates. When Su Rumo uncovers her mother’s “Abyss Sea Project,” she learns Gu Liyuan is the “abyss orphan to be erased” from the project, and the man she’s trying to save is exactly the “truth key” everyone wants to destroy.
