Reborn: The Goddess Rises

Well, after watching it for a while, I didn't understand some of the settings. First of all, what is "company"? Apparently it's not the Shen family. The heroine, Bai, and the scumbag in her previous life all have positions in the "company" and the scumbag in the heroine's previous life has his own company. So it should be a so-called alliance? So what does it mean that the male protagonist is the leader of the alliance? Then the question arises, Bai's operation is not secretive (except for the love-brained heroine script that is purely decentralized). I don't think that this kind of operation is other member companies (or shareholders, if my guess is wrong and the "company" belongs to the Shen family or the heroine's family, although it may not be likely). Having said that, if the Shen family is really just a member of the "company", then how can it be considered betrayed by Bai and the scumbag in the previous life? Bai didn't operate it secretly in the Shen family... I really don't understand. Will there be any setting additions later? From my perspective, Shen seems to be the one who got killed. Also, do the heroine and Bai know each other at the beginning? They say hello in the "company" and say they grew up together. My biggest puzzle is where Bai and the scumbag in the previous life worked. Thank you for your help.
