The insert song for TV Asahi drama 'Hyochakusha' (premieres July 23) will be Nakashima Mika's new song "Shiritai Koto, Shiritakunai Koto."

The story of 'Hyochakusha' revolves around a mysterious man named Hemingway (played by Saito Takumi) and the incidents surrounding him. Its insert song "Shiritai Koto, Shiritakunai Koto" is a ballad that was written by Akimoto Yasushi, who is in charge of the drama's original work and script. Akimoto wrote Nakashima's debut single "STARS" in 2001 as well as "WILL" in 2002, marking their first time working together in two decades. 

Nakashima commented, "The song is linked to the drama's content, so I love this song."
