Taira Kazunari (played by Hagiwara Rihisa) is a taciturn boy, but his silence is not because of his cold personality, but because Taira has a slight stutter, and his symptoms will be aggravated when he is nervous.In order to prevent this secret from being known to others, Pingliang always chose to keep silent in school.Fortunately, Pingliang grew up in his mother's meticulous love, so although he has small physical defects, Pingliang's character is very cheerful and optimistic.

In the third grade of high school, Taira was asked to introduce himself in front of his classmates. Just as he was blushing and falling into an embarrassing situation, the bad atmosphere was broken by Kiyoi Kanade (played by Yagi Yusei) who broke into the classroom.Among them, Ping Liang was relieved.From then on, Pingliang became the slave of the small class group headed by Kanade. He was ordered around and drank all day long, but instead of feeling uncomfortable, Pingliang actually enjoyed it.
