Kanjani8's new song "Kimi to Mitai Sekai" has been picked up as the theme song for Fuji TV's upcoming drama 'Shitteru Wife' to premiere on January 7. 

'Shitteru Wife' is based on the South Korean drama 'Familiar Wife', which aired on tvN from August to September of 2018. It tells a story about a man named Kenzaki Motoharu, who is not happy with his marriage as he suddenly slips back in time and ends up marrying another woman. Kanjani8's Okura Tadayoshi plays the protagonist Motoharu, and his wife Mio is played by Hirose Alice. 

Okura, who helped to write "Kimi to Mitai Sekai," commented, "It's been a while since Kanjani8 sang a love song. While the drama goes back into the past, I hope that this song helps to light up a brighter future."
