Yonezu Kenshi has penned the theme song "Pale Blue" for TBS's drama 'Rikokatsu' to premiere in April. 

Starring Kitagawa Keiko and Eita, 'Rikokatsu' is a love story about a couple who decide to get married without dating. After holding a fancy wedding, the two begin their lives together, but they find themselves getting into huge arguments over their differences in lifestyle, values, and others. As such, the two decide to get a divorce, but are unable to tell anyone around them. Secretly, they begin preparing for a divorce, also known as 'rikokatsu.'

Yonezu commented, "The concept is a love that begins with divorce, so I wrote a love song for the first time in a long time. I am already looking forward to the drama and how it will sound in it."
