A commercial for Fuyu Azuma's manga Kao ni Denai Kashiwada-san to Kao ni Deru Oota-kun, directed by Yui Kinoshita.

Meet Kashiwada-san, a female middle-school student, who remains emotionless regardless of how she is meddled with.
And Oota-kun, unable to control his facial expressions, is the complete opposite of Kashiwada-san--but he keeps messing with her, against his better judgment?!
