Shimotsuki-san wa Mobu ga Suki

After school, Kotaro Nakayama returns to school to pick up something he forgot and finds Shiho Shimotsuki asleep in an empty classroom. Shiho is rumored to be Ryoma Ryuzaki’s crush, a popular boy who has formed a harem in his class, but she is always expressionless and no one has ever seen her smile.
