The senior sister she was jealous of protected her at the last moment.
The senior sister has never complained about her, and she will think of her even if she has something fun and delicious to eat, but she has never appreciated it.
Until she saw her senior sister die at the hands of a monster to protect her. She was reborn, this time no longer for a man, this time for the senior sister!
Intention: I had a sudden idea to write a novel with two heroines about the senior sister.
