Sorry for being out of topic, speak of skilled actors, you gotta watch Jeong Nyeon. Whether you gonna like the story or not, Kim Tae-Ri's performance is outstanding there.
And speak about FbC, i'm touched when Ju-Won confront both mothers.
She said to Hae-Jun's mom that Hae-Jun isn't just live with their family, Hae-Jun really complete them as a family, something like that. And it'll be better if she (Hae-Jun's mom) will meet her son, it'll mean a lot for him.
Then she also tell San-Ha's mom to not disturb San-Ha anymore, since she have handover San-Ha to Ju-Won long time ago. A line that San-Ha never able to stand for himself.
