Episode 3/4 I love how blunt and go-getter the Yoon sisters are Chowon is just as blunt as Ji Eum/Ju Won is lol.
I wasn't expecting to cry at Ji Eum hugging her previous life's mum but holy And then nearly again at the end of ep 4.
It's been quite a while since I finished the webtoon so I can't recall exactly down to the specific details how the story goes/how meticulously true the drama is staying to the webtoon but I believe the brother bit doesn't last that long thankfully but pacing tends to need to be rejigged a little anyway, to fit a many episode webtoon into a much fewer episode drama
(I can't seem to get the spoiler tag to work! :()
