You can't blame her for being emotionally draining, she's a pregnant woman and suffering from unstable childhood. I just hope Doo-joon decide to take them on a vacation for a short break.
Probably because she's at the age of marrying that's why she's trying her best to keep her image by being professional. Not all people have the courage to open up with people, they're adult not a teenager.
I love it when author pull that twisted storyline card
I- hated the twist I kinda wanted it to be real ╥﹏╥
