she is getting married to him because she wants him to become the emperor instead of her brother. everything she has been doing lately is to set them up for success, such as making connections with the empress and changing the opinions of the nobles etc. She is going to the north so he can finally meet the woman he lived in his past life. i suggest you re-read the manhwa
Ah, I see. That's less confusing.
The reason she made that random guy divorce his wife and marry that lady she chose was to plant the lady as a spy somewhere
Ohhhh. Thanks!
Nppp
Dude, This is so fucking confusing. I got the drift at first with the helping ML become emperor but in the recent 20 chapters I've been so confused with what has happened. Like why'd she suddenly get someone married? What's up with the empress backstory crap? I don't get it. I don't want to drop this but jesus- I can't keep up. This is really some advanced plot.
