This story became bland when emperor say to keep harem stable he have to keep his concubin...

She's from our world 21-century so he can never understand her thinking.

You want us to understand a man to keep him a harem where woman have to share one husband? Even if she reincarnated she doesn’t have to understand man like that which cannot control his own little brother thoo (╯°Д °)╯╧╧ go to hell to understand stupid man like that

They let their wives go at each other without interference so they wont notice that he's the only one thats benefiting I'd rather be gay or stay alone.

Remember that little tsundere princess chu from west Yan now they would make
a good yuri couple.Lol
