In the beginning, I had a hard time starting this drama. I actually struggled for the first 5 episodes because there is nothing interesting to rope me into it. I even wondered why it got high ratings, and also wondered why my friend highly recommended me to watch this. However, I kept watching and then I slowly warm up to the ML (he's so handsome and sexy in black outfits, anyway... hehehe).
I like the character development of the ML, from cold distant man and strict team leader to warm and firm boss as well as a loving and adorable lover because of his deep first love for the FL. I understood that his past that made him the way he is. , and delighted in him slowly falling in love with the FL. I love how much he cared for his team and friends. I think the best part of the drama is the brotherhood between the team members, both the Solo team and K&K team. There is not much angst (except for the FL's mum non-approval of the love relationship).
Overall, very surprisingly, I got to like the drama and fell in crush with Li Xian (the ML).
As for rewatch value, I will watch this drama again but only for the cute and funny moments between the ML & FL, as well as the K&K boy teams.
