    1. The amount of visible change we saw from the beginning compared to the end is astonishing. She truly changed her actions, words, and heart. That’s because she learned how to love. As Gang-tae said “you finally know what warmth feels like,”. And, now that she knows, why take it? Let the poor girl have her happy ending. While I would love for a season 2, the story wrapped itself perfectly with a bow on top. Every character grew mentally and learned what it means to truly love. It’s so deep 🙁 and I love it. Their relationship is unlike any other, yet is my most favorite of all dramas.

    2. The combination of her immersion to KMY character, knowing her (KMY) to well, her brilliant delivery, attitude, stance and alluring voice made Seo Ye Ji perfect for the role… i cant even see any halyu star can portray KMY as good as she did.

    3. I've seen how Seo Ye Ji act in Save Me, Potato Star and Lawless Lawyer and she attacked each character differently. You can't see a trace of Sang Mi in Soo Yong or Ko Munyeong and so on. That's why I really think she is one of Korea's brilliant actresses. She acts with a deep understanding of the characters she portrayed like Kim Go Eun. Looking forward to her future projects.

    4. Thank you, Seo Ye Ji for bringing Ko Mun Yeong to life. This character will forever live in my heart. You’re such an amazing actress, I can’t wait to see more of your projects. Fighting, Unnie! 💓💓💓

    5. How can i ever get over ?!
      How can I not love her .
      She literally is the best thing happened to me in 2020 !
      My lady love seo ye ji, I wish at least once I could tell you how much I love you ❤️
