8-jou no Carnival

Ryokuta Hanazawa is a high school student who rarely draws attention from others. Seated beside him is Shio Mizuno, an academically gifted and talented student. One day, Ryokuta sees Mizuno dancing in costume and wearing a mask in an empty section of a park. He later learns that she posts these performances online under the name Smile. Inspired, Ryokuta begins recording his own dance videos from his room, also anonymously.
