Song Zhiyi is really annoying.
Meng Xi has hated her since she was a student and competed with her.
After a dream, she realized that she was living in a novel.
Song Zhiyi is the heroine and a natural winner.
And she’s just a nasty supporting actress who needs to be brought down.
There’s nothing wrong, the heroine and the supporting actress are not born to deal with each other.
Meng Xi became more and more difficult for her, poured her red wine at the banquet, and asked the bodyguard to send her brother to the hospital…
The worst part is that he kissed her when he was drunk.
I don’t know when, everyone thinks they have a leg.
Meng Xi sneered at them: “Bah!”
But Song Zhiyi himself said, “Meng Xi, what kind of relationship do we have?”
Meng Xi was cold to her… unable to get cold: “…”
The arrogant and domineering young lady and the pitiful black and white lotus.
It’s cookies, it’s a weird two-way crush.
