    I just finished first Ep. Fighting, fighting,fighting. Can I say first Ep make me disappointed. How you can make character of a lead actress in 2021 nowadays be like that OMG . OMG. Fighting

  3. 3 : Bona Says:

    First episode only and we see shit already! What a bastard.

    And here she is, happily putting her lipstick on just for him, when she is about to meet him!! Forget about him, girl. You should be so lucky this bastard got caught now, not later.

  4. 4 : Bona Says:

    Oh what heartbreak! This 2nd episode is so sad to watch. Denial, anger and pain all at the same time, for both the girl and the one who broke the bad news to her. 💔

    I feel so sorry for Yoon Song Ah. She trusted the bastard and he played her out in the most cruel way. Makes my skin crawl. Oh god! How can he be so heartless. Its an innocent person he’s hurting.

    Oh god! Never mind, Song Ah. If you must cry, cry then to celebrate the fact that you are lucky. You got away from him just in time! And remember to throw away that lipstick too.

    Time to change your lipstick. 💄💄
