I wrote this paragraph after watching the first few episodes:

I struggle with Pilot episodes about 99% of this time, but the first episode of this drama did not disappoint. The cast is stellar and each episode has me wanting more and more. There are also very few dramas in which my mom gets interested in, but she has insisted that we wait for her to watch each new episode and it really has become a family event. I think the topic of the drama is quite interesting with the focus being in this new up and coming start-up world. The acting is superb (especially by our two male leads -hearteyes-), and the music adds such a nice touch to the drama as well. Right now, second lead syndrome is hitting hard, but I guess we can never be too sure how this will play out. Definitely regretting starting the drama when it wasn't fully out yet, but also something wonderful to look forward to each weekend.

These are my thoughts after finishing the drama:

I still loved the drama, but I think it helped that I didn't invest myself in reading up on all the fan / ship wars that apparently broke out because of this drama. To me, this was a drama that provided solid entertainment value during my weekends of relaxation. Both male leads did an amazing job in really getting me to want to root for their happiness. I agree that there were definitely things that could have been given more development, but if every little thing had a reason in this drama, the drama wouldn't have been able to conclude in 16 episodes. To me, this drama had one of the few satisfying endings that I've watched, and I think it tied everything together nicely. By no means is this a drama that's meant to make you think the impossible can happen -- it's very predictable, but most k-dramas are, to be honest. Maybe I'm too simple-minded when it comes to my dramas, but reading other reviews makes me think that ... well, if you think too much about every little detail of this drama, you can easily come to hate it. However, for the beautiful cast and solid acting, it's definitely left me curious and interested in the other dramas of our main leads!
