[Big heroine] + [Group portrait] + [No male protagonist] + [Funny] + [Watching others fall in love] (Note: There are bl elements)
The vicious female supporting character just continues to be a playboy, and the cannon fodder gets out of the way.
I was originally from a different world, traveled through the novel, and became a vicious female supporting character. After the original owner tortured his six brothers, he gave up playing. By coincidence, he allowed himself to penetrate the original owner's body. If you inherit the hatred of the six older brothers towards the original owner, you will face endless humiliation and torture.
But I am not the original owner, and I did not do the bad things. Why should I bear all this? No matter how miserable my brothers' fate is, no matter how miserable they are, no matter how they attack me out of hatred, I will never show mercy.
