She didn't accept his proposal and was about to punish the guy but she decided to forgive him.
She forgave him but rejected him as she should've.... think she was just shocked by his random, honest outburst
I went red the comments that contains spoiler, she's really going to marry that guy? What the heck.
Spoiler:
It's for several reasons: First because Paulina wants to maintain his surname 'Winter' and marrying a man with her equal status will want to change it or having their kids having their name and not hers. Maybe a younger man will accept it but Paulina does not like someone young than hers. Secondly, the doctor does not have a family so less problems for Paulina about in-laws. Thirdly, he stated what he wants from the marriage and Paulina can give it, he will not (in principle) not betray her if she give him money and status. And least but not less, Paulina is alone and
vulnerable without any family, it's seem so easy that she say 'Why not?' [...].
Wait so he legit said he wants her for her money and title and she still goes for him???? Damn I thought she was smart but she just dumb like wtf
