I put on a cat mask when I wanted to cry

Miyo Sasaki (Mirai Shida) Dubbing) is a sophomore girl in high school. Because she always hides her true emotions in her heart, Miyo is called the "Infinite Mysterious Person" by her friends around her. In fact, Miyo is a girl who cares very much about other people's opinions and cares about the people around her all the time. Miyo has a crush on a boy named Hinode Kento (voiced by Natsuki Hanae), but Kento's attitude towards Miyo is very cold. In fact, Miyo keeps a secret. She once got a cat mask from a mysterious businessman. As long as she puts on this mask, Miyo can turn into a cat. After turning into a cat, Miyo always likes to go to Kento's home because she finds that although Kento is indifferent to humans, he is particularly affectionate towards cats. Miyo becomes more and more obsessed with spending time with Kento as a cat.
