Survival Raft: Why Is My Landlady Here?!

The oceans have turned toxic, spawning nightmarish creatures that brought civilization to its knees. Now the world is drowned—every continent submerged beneath endless waves. Humanity's remnants drift on makeshift rafts, armed with nothing but fishing rods and desperate hope, salvaging supplies from floating crates. Tang Feiyu expects to fight this apocalypse alone, but when he opens his eyes, his beautiful 28-year-old landlady is standing on his raft. As they navigate six deadly stages of this waterworld nightmare, survival becomes far more complicated than he ever imagined.
