[DeepL Translation - needs review] The one who fulfills my desire is the sister who is the exact duplicate of the person I love.
A love triangle between an honor student sister and an impudent younger sister.
I, Yuka Amemiya, confessed my first love, Nagisa Hanabusa, and was rejected by him.
I was so disappointed that Nagisa's younger sister, Kaimochan, who was a close friend of Nagisa's, made a proposal to me.
I'm going to make you forget about your feelings for your sister.
I can do to her...
