Kaishagaeri no Pas de Deux

35-year-old Toru Kohinata, lacking in physical fitness, has a personality that can't refuse. He finds himself attending a ballet trial lesson at the invitation of someone, only to wake up the next day with sore muscles. Thinking he should give up, he witnesses his coworker Honoka Sakuragi dancing in the company's document room. Moved by her performance, Toru decides he wants to dance ballet seriously. However, when Honoka discovers a photo he accidentally took of her dancing, she accuses him of "voyeurism."
