In this drama, there is "Sandbox" event.
In Indonesia, there is also similar event: "1000 Digital Startup", and I also ever joined the event
The point is it is very good to see that the event in the drama is quite similar with the event that I joined. So, I understand the thrill when finding teams, hackaton, etc.

I am also a Software Engineer and and also ever joined Mathematics Olympic. It is like I quite understand what Nam Do San feels.

Pro of the drama: Episode 1,2,3,4,5,6,7,8 are very very good. Not only it brings so much emotions, but it teaches us how to run start up from the start, how to manage the share, how to be good leaders. I truly amazed on how this show does research about everything and so detail.

Cons of the drama:
- Person like Nam Do San who has almost all IT skills in 1 person literally does not exist in this world. He even can save company from hacking in 1 day. Not only that, he can revamp the self driving cars algorithm in a week. Not only that, he can run a program in a device where even tetris cannot play. This is something that I laugh and my friends also laughed at this. They try to create a story where there is 1 super person that nobody can compete with. It is too good to be true, for me.
- eps 9/10 is just downhill for me. The drama maybe expect the watchers to cry when Seo Dalmi found out the truth about 15 years ago. We already expect Seo Dal mi will be disappointed (we already know this from the first eps), but we expect something more, beyond our expectation. But, instead they make these eps just dragging until the end. I feel this is very boring.
- In either eps 11 or12, there is a scene where Nam Do San hit HJP. I feel this is off. Something I missed probably. Nam So San might be thinking of Seo Dal Mi a lot, but what HJP does is actually helping Seo Dalmi. There is no reason to hit HJP. I thought Nam Do San is a logical person, but they changed this person in this episode. Because of love....
- There is a problem in the drama that say they will have more cost because there will be lots of users that use the program. Again, I feel that this is unrealistic. No one in the company suggest offline mode? No one in the company suggest trial mode? No one suggest limit per day mode? No one suggest for lite mode? Seriously?
- The text-to-speech program that introduced in the drama, is just to perfect to be true. And this is also develop by Nam Do San alone. Again, unrealistic for me. Even natural language program is currently is being developed by Google, but Nam Do San does this alone (and by their small team).

Overall, I am quite happy when there is drama that has a digital theme. I like the emotion it bring and also the knowledge it shares to us. What I don't like is the exaggerated skill Nam Do San has (maybe because I also an IT), and eps 9/10/11 that feels boring.
