"I am liking this drama so far. Its my first time watching the two lead actor, they look really good. At first, I am quite lost with all the family ties, business names, and everything but I guess I figured it out after ep 2. I am curious about how the story would turn out. Lee ha nee's character reminds me of hong cha young. hahah both crazy and badass" "Best hilarious scene is that Yeon-joo speaks Vietnamese language with Trang behind her evil mother-in-law and she totally doesn't understand a word lol I almoat burst out laughing when I saw that scene, rewind it back twice ?"
"Wahhh i just realised the title is One The Woman = wonder women, i just finished watching 2 episodes and the story are awesome,, looking forward for the episode. I love both lee ha nee both characters, strong yeon joo weak mi na, and the ml looks younger and more handsome with that hair style. Hope yeon joo can avenge to mi na's family in laws as she is mistreated. Mi na such as nice girl when she is young age :D. Stay safe everybody, together we fight covid-19 ^_^"
