Most people here blame Luke for everything. But honestly, if SZT was a man I‘d run in the opposite direction as fast as I could. Which woman would want such a partner? So why is Luke mainly to blame? Some of what he says is definitely too harsh, but honestly if Flora were a man and were your partner would you just swallow everything she does and go happily about trying to be a couple?
Whenever did he call her easy after she was sexually harassed?
First, he said you LOOK LIKE, not you ARE, meaning to someone who doesn’t know her she could seem. Second, he said „easy to pushover and control“, not „easy“ like in morally loose, meaning she’s too helpful at work letting others give her tasks no one else wants to handle. Third, he never said that after he knew she was actually harassed, so you’re taking it completely out of context.
I love Luan Nian the way he is. He cares deeply and helps and supports SZT at every turn, from the beginning onwards. He is sweet at taking care of the dog he never wanted. While SZT keeps shutting him out, putting walls between them time and again. This behaviour might have made sense in the book, but definitely not in the drama because drama Luan Nian is such a caring and supportive partner.
I don’t really like SZT. The way she is written doesn’t work somehow. I can imagine it worked in the original novel, because Luke was different, but here it doesn’t work.
