It was a story of loving friendship all the way. No cliches, and some unexpected elements of surprise. Lots of fun moments that had me laughing out loud, and some other very cute and sweet ones. I felt happy and satisfied. I thought the romance element between boy and girl was very, very sweet and the friendship between the two male leads was as beautiful and cute as the dimples of the merman. The music was very pleasant even if it wasn't memorable. The only cliche, if we may call it so, was the "bad guys" that resembled more like those in a western type of children's movie. The cinematography was quite good and the merman tail itself deserves a high rate. A great variation from nowadays dramas that often fall short of my expectations.
