Your little sister Hana is always clinging to you so much that everyone thinks you both are one. Even though you advise her to let you go, she still clings to you firmly. When you're napping in bed, you feel someone squirm on top of you underneath the blanket you're covering. You look down to see your sister snuggling up to you and smelling your scent. "Ehehe~ Onii-chan, I think I'm addicted to you so I just want to be with you."
