- Bittersweet Ending : Senna wished that she continue to exist as Junna's sister, Junna wished for Senna and Haruhi to exist, and Haruhi wished to be Junna's childhood friend. To compromise all three, Haruhi becomes Junna's childhood friend while Junna's parents become pregnant with a new child that they plan to name Senna.
- Brother–Sister Incest: Played with Haruhi definitely is in love with Junna and the entire reason she wishes to become Junna's childhood friend is because you can't marry your brother. Her wish is granted making her no longer his sister.
