Tidal Covenant: The Sea God's Little Princess

Few short dramas commit to the drama quite like this one does. On the surface this is a Family / Fantasy serial, but underneath it is a story about obsession, loyalty and consequences — and "Tidal Covenant: The Sea God's Little Princess" plays both layers for all they are worth.

Mavis is a little mermaid with the Sea God's trident mark and no family she can find. Saving the Queen earns her suspicion and exile instead of thanks, which tells you everything about this court. The abyss overlord massing beyond the reefs and a traitor princess selling secrets give the kingdom real trouble, and when Mavis's divine blood finally wakes, the mother-daughter reunion lands with the full weight of forty episodes behind it.

Tropes on the menu: family bonds, strong female lead. Come for the premise, stay for the whiplash — every episode ends with a reason to hit next.
