I am the male protagonist of this novel. I have nothing but good looks. I am sought after and welcomed by girls everywhere. Being handsome brings me endless troubles and worries. In fact, I just want to live an ordinary life.
However, my "prospective girlfriend" Yang Shiyu is a popular member of a nationally famous idol girl group. She is a mermaid princess who came to the mortal world to escape her engagement.
The seven knights chosen by the human family in contracts since ancient times guard her secretly and prevent her from falling in love with humans. Just as the first knight appears, a bizarre secret room murder also ensues!
I, the most handsome and useless novel hero in human history, may solve the most complicated serial murder case of an idol group, win over the most unruly mermaid princess, and defeat the seven knights who protect her with the most handsome appearance!
