Dear reader,

This novel genuinely surprised me with how atmospheric it feels. The undersea setting is not just background decoration — it constantly feels oppressive, isolating, and deeply unsettling. The deeper the story goes, the more the station itself starts feeling alive in the worst possible way.

Muhyeon, a dentist assigned to the station, quickly realizes something is wrong with both the environment and the people around him. The tension builds slowly at first, but once the story shifts into survival mode, it becomes incredibly hard to put down.

One thing I especially loved was how the novel balances moments of warmth and humanity against the overwhelming darkness of the deep sea. Gumi in particular helps ground the story emotionally amidst all the tension and paranoia.
