I learned many lessons in this series. 1. Don’t be afraid to fall.
The series is set in South Korea’s own fictional Silicon Valley called “Sandbox,” a start-up ecosystem founded with the purpose to help new and bright entrepreneurs. The idea from this stems from an actual sandbox, which allows the person on the swing to fly as high as they can. If they were to fall, the sand would prevent them from getting hurt.
In reality, not everyone gets a “Sandbox” in life to keep them from falling and hurting themselves, but we don’t always need to be so afraid to fly. Dal-mi’s father, Seo Chung-myung (Kim Joo Hyun), is a prime example of this. As a struggling entrepreneur who'd dreamt of making it with his bright ideas, no one had believed in him at first but himself, and yet he was never afraid of falling. The actors did a great job in portraying the characters. Team Dosaan!
