あらすじ
The one who fulfills my desires is the younger sister of the person I love―. A love triangle between the perfect older sister and her care-free younger sister. I, Yuka Amamiya, confessed my feelings to my first love, Nagisa Hanabusa... but I was rejected. Unable to let go of my lingering feelings, Nagisa's younger sister and my friend, Mino-chan, made a surprising offer. "I'll help you forget all about my sister." She offered to let me do everything I had wanted to do with Nagisa — but do it to her instead.
