Ota frequently makes fun of his classmate, Kashiwada, because her expression never changes. However, his prank never succeeds, mainly due to her getting clued in by his own extremely expressive face. Unbeknownst to them, Kashiwada does change expression, but can be hardly noticed, including her crush towards Ota.

• Hiyori Kashiwada • Shiori Mikami (PV), Akane Fujita (anime) • Usually referred to as Kashiwada-san by others, she is a seemingly inexpressive girl, whom nobody knows what she is thinking. Instead, most of her expressions are conveyed through her twin ponytails. She and Oota were classmates in kindergarten, and she felt sad when he moved away. She had been attached to him since their kindergarten days and was happy to be reunited with him in high school. • Akito Oota • Daisuke Kishio (PV), Kyōhei Natsume (anime) • Usually referred to as Ōta-kun by others, he is a mischievous and selfish boy who is very expressive. He is very easy to read. He is concerned with Kashiwada's inexpressive face and has been trying to make her let out expressions, but to no avail. • Tadokoro-kun • Yūya Hirose (anime) • Oota's friend, who, despite being very optimistic and laid back about almost everything, is also a worry-wart. He questions things Oota does to Kashiwada, but does anything Oota commands him to anyway. • Sata-kun • Sōhei Horikane (anime) • Oota's honourable student friend who has calm demeanor. He loves to observe Oota and Kashiwada's interactions. • Tabuchi-san • Yumiri Hanamori (anime) • The class president, who loves Kashiwada. She thinks Oota is bullying Kashiwada, and has been trying to protect her. • Odajima-san • Mayu Mineda (anime) • A high-spirited girl who is able to read Kashiwada's feelings, but also the only one who is oblivious to Kashiwada's feelings towards Oota. She also likes to see Oota's flustered expression, but she also blushes when Oota does things similar to romantic advances towards her. She eventually realizes that she has romantic feelings towards Oota. • Oota's older sister • Shiori Mikami (anime) • Oota's older sister who frequently shows grin on her face and loves to teases her younger brother. She also tries to develop relationships between Oota and Kashiwada—messing with them while at it. • Kashiwada's older brother • Daisuke Kishio (anime) • Kashiwada's older brother who dotes on her. Like Kashiwada, he shows lack of emotions behind his smiling face.
