This article is about an imaginary dynasty. The heroine is an illegitimate daughter of a wealthy family. She was abandoned to the opera house when she was young. She was taken back to the family when she was five years old. However, she still associates with the opera house against her father's wishes. She is the lowest performer. When she met the male protagonist with her half-sister, her heart suddenly fell in love. By some strange combination of circumstances, the male protagonist falls in love with his sister, but the sister only falls in love with the female protagonist's senior brother, so a sadomasochistic relationship is inevitable.
Then, the male protagonist asked to marry his sister, and the female protagonist not only wanted to fulfill her sister and brother, but also herself, so she married the male protagonist on his behalf.
I thought that the first person who got closer would get the better life after marriage, but my sister came back after being tossed... Where should the relationship between the four of them go?
After all, it's just love to the core, so who's wrong? There's no regrets in falling in love once and for all.
