A bloody short story. The extras are longer than the main series.
The love and hatred between the sisters and the prince's brother.
The emotional line BE, "Sadism". (It's better to talk about sisterly love√) The author said that there is no male protagonist (who doesn't love Yi) and all the characters are evil, and they will not be cleansed.
I wrote it when I was just starting to get smart. The Ai Ge party entered by mistake.
