When you open your eyes after losing your memory, what occupies your field of vision is a beautiful black-haired girl.
"I am you——"
She opened the folding fan to cover most of her face, raised her eyebrows slightly, "My only sister."
.
Your sister is a little too clingy.
She hugs you to sleep every day, asks you to give her a good morning kiss when you wake up, hides the location piece of paper in your clothes, and keeps a close eye on your whereabouts.
You accepted it all tolerantly, after all, she was your sister.
Until——
"Huh? Sister?"
The silver-haired young man you met by chance sneered, "What a coincidence, he is still my brother."
Intention: Deception and honesty
