Kimiko sings "Dream a Little Dream" during a fantasy scene in the season one premiere. Later in the season, while in the hospital, she daydreams and performs Judy Garland's "I Got Rhythm" with Frenchie (Tomer Capone).
"I grew up taking singing lessons in high school and middle school," Fukuhara told Variety. "In college, I was part of an a capella group. I love singing, I just have terrible, crippling stage fright when it comes to singing in front of a group of people."
It took one day to film the musical sequence, and Fukuhara told Insider that she "never would've thought my character would partake in any of those things."
"All the rehearsals that went into it and just listening to the music, practicing the song and everything, it was an experience that I have never had before," the actress said. "It was a challenge, but it was a lot of fun."
