Aki-Sora: Yume no Naka

Sora Aoi has been carrying on a secret romantic relationship with his older sister Aki, hiding it from everyone around them. Their already fragile situation becomes more complicated when Sora's twin sister Nami pushes him toward classmate Kana Sumiya and tries to make him more involved with the Fashion Research Club.

Nami's matchmaking is not as innocent as it appears. She is struggling with forbidden feelings of her own, and the emotions shared among the siblings and their friends become increasingly difficult to separate from jealousy, secrecy, and guilt.
