This drama is so good that it made me decide to study computer engineering. I have watched this series during my highschool, at that time I was still trying to figure out the major I want to study for university. Even though many years have passed by, I still rewatched this for many times.
The movie is filled with dreams and passion of the youth entrepreneur who is trying to push themselves to be successful. It talks about 2 siblings, Seo Dal-mi and Won In-jae, that have a completely different life. However, they both end up starting a new business in a hackathon competition. I mean, with only this plot, I felt like it was already worth watching. But there was more conflict and drama in the drama. Like when Seo Dal-mi was a child, she made friends with Han Ji-pyeong who she believed to be Nam Do-san through the letters. When they grow up, something makes them meet again and creates a complicated relationship.
Besides the plot, the OST songs in this drama are compatible with each scene so well. The mix of a variety of emotions are getting along with the acting and some of the songs still remind me of each scene when the beat is up. Saying that this series has one of the best OST songs is not exaggerated.
All of the actors play their role perfectly and make the movie more enjoyable for me. My favourite actor here is Han Ji-pyeong who really dragged me into this drama. The actor's acting is flawless and it always reminds me of this character when I saw his face in another movie.
On the other hand, there are few things that I am not satisfied with in the drama. First of all, no matter how good your project idea is, there is no way that investors will spend millions of their money in your startup without knowing stuff like the business model and others. Besides that, the development of the characters are a little too fast. Even Sri Dal-mi have done some innovations but competing in their first hackathon and doing most of the things right is kinda odd to me. Moreover, the programmers team that left for a few years and came back to be like god level developers. Like them taking over the project that they did for years and done it in a few months, that is no way to be real.
Overall this is a really good drama and will definitely be worth your time. If you are into drama and technology, it will be even more enjoyable. However, if you are an engineer or tech student, it may be a little painful to watch since stuff in the movie is a little far from reality. All in all, it is a 9.5/10 for me because I still love the plot and acting.
