1. Yes!! This felt like an actual spy drama and had similar vibes with My Secret Terrius. But this one is different because beyond the spy and action, there were a lot of discussions on love and marriage. Actually it is like a relationship drama under the guise of a spy drama.
2. I loved the 3 main leads. Jihun, Ahreum and Derek had so much chemistry together as a team and separately as couples. The stark contrast of the marriage between Jihun and Ahreum vs Derek and Ahreum were both so beautiful, i actually got confused who she will end up with. I was team Jihun but i wondered how they will get back together without Derek in the way. I liked how they resolved this.
3. The bromance between Jihun and Derek was also great. They both loved the same woman although they had different ways to show their love. Hated Derek's character at first but came to also like and pity him in the end. I hope he is having a good life like he wanted.
4. Although Jihun loved Ahreum he never crossed the line and waited until the time was right. They were too young when they got married but now they grew up, got to know each other more and found out thy actually worked well together. They looked like the korean Mr and Mrs Smith in the last episode. Really loved the acting of Eric in this drama.
4. Ahreum is one of the best female leads in 2020. She was smart and tough, yet feminine and compassionate. She fought Tinker and slashed his leg with a pair of scissors, she made a sweet deal with Kim Dong Ran and helped take down Helmes boss. I actually thought she would get out of the wedding dress business to be a full time agent in Jimin's team but being informant is way better!
5. Yonggu and Seora ?

Dislikes: The bad guys didn't get what they deserved.
