At first, I wanted the title to be XX Three X, but no matter how hard I tried, I couldn't think of one.
So I decided not to force it. Smile (too weird) → poker face versus poker face (because the protagonists are both poker-faced) → then let's just call it Two Poker Faces → (a flash of inspiration! Add Tezuka, who's just making a cameo) Three Poker Faces
There's not much to say in the blurb. This one-line introduction sums it up: When a girl with emotional detachment syndrome meets a smiling, scheming bear.
Turns out they are sisters~~
Both heroines have the word "jing" in their names...
