Nanase and Yuni are secretly dating. Yuni understands that her girlfriend, who is busy with the volleyball club, has her own commitments. However, she can only spend her after-school hours quietly, yet feeling lonely. In this unspoken romance and with her surplus time, she continues to post on her private account. Selfies, complaints, and a little bit of bragging about their relationship. Anyone will do. A modest expression of her feelings. But when this gets exposed at school, Yuni finds it increasingly difficult to remain just Nanase's girlfriend.
