Inexpressive Kashiwada and Expressive Oota - S01

Oota-kun is an open book; his face shows every thought and feeling. Kashiwada-san, by contrast, is impossible to read, since her expression never changes, no matter what happens. Annoyed by Kashiwada-san's endless blank look, Oota-kun makes it his mission to break through her calm exterior, trying every prank and trick he can think of, from fake spiders to ridiculous text messages and everything in between, just to get a reaction. As Oota-kun's endless attempts fail to crack Kashiwada-san's unchanging poker face, their back-and-forth becomes part of the daily routine. What he does not know is that his antics sometimes do manage to draw out a faint smile, and he fails to notice that he had already gotten through to her from the very start.
