My Bodyguard Is a Prince from Another World

Antique bottle links to dying merfolk realm; modern aid saves them but cracks the barrier.

An antique bottled ship in Sophia's possession becomes a lifeline to Thalassia, an undersea civilization crumbling into ruin. She channels contemporary resources through the narrow neck, stabilizing the ecosystem and winning the merfolk's devotion as their Storm Goddess. The miracle turns precarious when colossal leviathans batter the fragile glass from outside, splintering the only passage between worlds. Meanwhile, a mysterious presence moves through both realities, hunting the secrets that bind them together.
