" I wanna hear your song " had a nice mystery but the main story was so so.

First of all, the mystery was pretty interesting. They handled the pace pretty well and they presented the whole mystery thing in a way to keep things interesting till the very end. However, the romance was so so. And the love triangle wasn't well developed. In addition, the side stories were not interesting enough to be entertaining or add something to the story. Finally, the performances were really good.

So, overall, seven out of ten.
