I got recommended this on netflix and started watching expecting a story about passionate people chasing dreams. I completely misjudged. Was surprised but impressed with the emotional impact of first episode. Apart from that, the only watchable episodes are during which the leads participate in Hackathon at Sandbox- the fictional startup incubator. Everything else is about the love-story, which shows us all wrong reasons or no reasons at all to fall in love with a person. There is no real love through communication between Dalmi and Do San, it's all physical and horny. Dalmi completely ignores the person whom she was able to have meaningful conversations through letters in her childhood after she finds out who the person is, and is shown to miraculously forget about all of it in one episode. The end result is that you are most likely to drop the drama after running out of patience as there really is no redemption or character development for Dalmi-DoSan, who continue to exploit HanJipyeong at every possible opportunity, only to discard him after their job is done.
The only saving grace is top-notch action from Kim Seon Ho, who will make you root for him in every scene he appears, only to receive insults and injustice from other characters(except Grandma) and break our hearts. Idk what the writer wanted to convey, but the message I got through the story of Jipyeong is that it isn't worth always being kind to people, as they'll end up taking you for granted and even exploit you to the point where you're left with nothing.
I watched until episode 12 and after that only scenes of HJP as the lead-pair became truly annoying and the story easily predictable.
