There is a love triangle between an excellent elder sister and a non-serious younger sister. I, Yuka Amemiya, confessed to her first love, Nagisa Hanabusa. she was rejected. She couldn't see me in my lingering smoke, so she had a proposal from Kaimo, a younger sister of Nagisa, who was close to her. "I will make you forget how I feel for my elder sister." She said that she can do everything she wanted to do as Nagisa. She added the shadow of her favorite person to her half-sister and went on a date with Kaimo dressed as Nagisa. "Yuka senpai kisses her important friend who thinks like a younger sister." She gives her greed as if she is drowning. While talking as "substitute for Nagisa," she is gradually attracted by Kaimo herself.
