Contrary to how the summary may come off as, the FL most definitely does not have low self-esteem in the sense where she's unconfident. She is extremely spunky and smart. Like truly strong and smart, not the Mary Sue kind. She's very very capable and does NOT let anyone walk on her. This story is cool because it isn't about some cheap or dramatic romance. It's not very fluffy or super romantic. There's a lot of growth among the people in there especially the main cast. The ML's fear of marriage isn't just a quirk. it's a huge psychological issue that they take a lot of time to address. It's stemmed from trauma and he literally falls into panic attacks when it comes to things related to marriage. This fear of marriage takes a huge toll on his relationships and mental health.
On the FL's side, she is traumatized by love ever since the male lead left her on their wedding day five years prior to the start of the drama. Even with a loving boyfriend, she has a hard time fully falling into love with him. In the summary it says she leaves him because he cheated. It's not as black and white as other dramas. He did cheat but they both realized she was incapable of truly loving him anyway and remain as friends afterwards. He's not a bad person, just someone who made a really bad decision. The FL realizes that if she ever wanted to truly love someone again, she had to forgive the ML. They clear their misunderstandings when she learns he has a serious psychological issue with marriage and they become confidants in each other and good friends. They do end up together in the end but it's not stupidly dramatic. I think the FL is hilarious and I admire her savagery. Sunny Wang did a great job playing this role.
I've never really seen Han Geng's act. My impression of him is stuck in OT13 Suju LOL. I must say, he did a pretty good job. Like it was way way better than I had thought. He feels like an actual actor and I'm pretty proud of him. I like how he didn't choose some trashy drama to star in. This one doesn't have mushy love so it might not be as popular but plot wise, I enjoyed it.
One of my main complaints is, some of the script gets a little preachy some times and the music can be cheesy but overall it's a solid drama that offers multi-dimensional characters.
