It's July of his second year of high school. Yotsuya-kun develops feelings for the girl who sits at the front of the class. Her name is Shirogane-san. They're both members of the beautification committee, and although they don't talk much, his gaze seems to follow her whenever they're together. However, Shirogane-san always wears a mask while at school. What is she hiding? From a popular Twitter artist, it's a "mekakure" (hidden eyes) young love comedy! Note: Volume 2 contains the side story Fuukiiin no Nichijou (風紀委員の日常)
