In November 2018, Sexy Zone member Matsushima Sou was diagnosed with sudden panic disorder. He decided to take a break from his activities to focus on treating his illness. After a year and nine months of treatment, Sou has recovered and is ready to resume his career.
Sou will make his comeback in stages. He will not be participating in his group’s “Sexy Zone POP×STEP!? TOUR 2020” tour in September though.
