The ending was a JOKE. I love happy endings, that's why I watched the 1st and then final episode first. I've watched a lot of Mermaid movies and dramas from different countries, even watched the cartoons and never seen a mermaid fall in love with another guy. I grow up with the knowledge that Mermaids / Merman only falls in love with one person in their lifetime, even it's a failure or successful love. Because it's their FIRST LOVE.
The writer didn't give the "Mermaids First Love" a justice. What a joke! LOL!
You'll regret watching this.
