Please recommend a modern romance novel where the female protagonist is reborn.

I found it, no need to answer, thank you In her previous life, the ex-husband of the female protagonist (not the male protagonist) had a very good relationship with a female friend. She liked the scumbag but helped him chase the female protagonist. After the female protagonist and the scumbag got married, she was still very close to the scumbag. The female protagonist got pregnant and had a miscarriage. She dumped the scumbag and dated the boss of the online game company above the scumbag's company. [Clue: There are several 'she's in the introduction. It starts with the word' she'. The female protagonist's family seems to call her Xixi. The male protagonist's mother and the female protagonist's mother are classmates. The female protagonist's ex-husband works on the 14th floor. The male protagonist works on the 15th floor.]
