Blue Fin Century

Three hundred years ago, glaze mermaid princess Marina broke up with Loxien cruelly to shield him from usurper uncle Kevin, who ambushed and blinded her before locking her up. Three centuries later, Loxien became Sea God. Believing she left him, he wed her to get revenge, yet instinctively guarded her constantly. He later learned all her suffering was Kevin’s scheme. Marina recovered her sight.

HappyShort released it as 60 bite-size episodes mixing revenge, made to watch on a phone in one sitting or a few.

If you came for revenge, the payoff is the slow build to a payback that lands hard.

The whole series takes roughly 1–2 hours, so it's an easy binge.

Press play on episode 1 and DramaNext moves on to the next one by itself. No account and nothing to install.
