The manga Isshiki-san wa Koi o Shiritai (Isshiki-san Wants to Know About Loveadaptation anime confirmed this Friday (17).

Synopsis
The story follows Rinna Miliford Isshiki, a prodigy police inspector known as "Rinna of the Steel Face." Famous for her serious and impenetrable demeanor, she has always maintained a firm and professional image. However, lately, something has been shaking her self-control: the presence of Detective Meishi Rokutanda.
Despite trying to maintain her rigid expression, Rinna finds herself disconcerted by Meishi's gentleness and calmness. Confused by these unnamed feelings—and fearing that her "steel face" is beginning to crack—she decides to accept Meishi's proposal: to pretend to be in a relationship. The plan was just a charade… but will her heart cooperate?
