Well, the story is about harem so... but the women that became the main focus is only two of them if you could summary to this date chapters, Xue Lin is obvious since she is the FL, and Ruyan Liu is... well, let's say because the rice had been cooked.
Spoiler I will try to explain based on what I read in raw ending. At the end, the main wife give the company and the rest of assets to another successor... And join the MC and the rest of harem members... After God knows how many years... The MC return and manage to make several people gain their youth again... What is funny that most of the people that left behind still fear the main wife... Even if she smile... They feel fear instead lol
Harems are okay if they are out in the open. Even the ml knows he’s wrong that’s why he lies to the fl all the. I find him pretty sh*tty. He did have many feelings for her anyway, he should been honest and just did what he wanted. It’s completely wrong no matter how outstanding he is.
