There is another clean freak in Aoyama-kun's class, Narita Shion. Every day, he keeps his germaphobia a secret, avoids human contact as much as possible, and plays online games as he can't get dirty there. One day, in the home economics class, a super high-level cooking contest breaks out between Aoyama-kun and Narita. On top of that, Narita gets accused of stealing a girl's gym clothes. Will he be able to prove his innocence without revealing his germaphobia?!

Shion Narita est dans la même classe qu’Aoyama et est lui aussi un gros maniaque de la propreté. Mais contrairement à son camarade, il préfère garder le secret et chaque jour est pour lui une nouvelle épreuve.
