I came here to say for all the other bitter, poor reviews you might see scrolling through, let me summarize their major disappointment—it’s over a ship/pairing that was never intended to get anywhere between the MFL and SL (your typical second lead syndrome). If not throughout, then most certainly by the conclusion of the drama, you’ll Know exactly why that’s the case as well as how the overall story ties together with its characters growing from start to end. but. It’s a bit pointless to try to get across viewers who A) can’t bother finishing the drama mainly due to the indifferences of said ship, or most pathetically B) insisted on watching the show solely to skip scenes that were vital to the characters’ stories thus concluded there were “plot holes” and/or “inconsistencies”. Go figure, I suppose. There is also a whole other debacle debate as to whether the drama delivered good business models, and whether they’re applicable to the real world. What you have to keep in mind is paying close attention to the drama’s usage of its metaphors, because somehow it’s lost on the vast majority who fail to realize they can and have already applied them to the real world.
One perfect example I can give is the “Sailing off without a map” saying that’s referenced throughout. In short, it’s a metaphor mostly* for innovators, visionaries—people with idealistic views as opposed to investors who have realistic views. You either win big or lose big. And should you fail, you're one step closer to success as it is still a good experience to have, knowing or figuring out how to do better the next time. Failure is part of the process. It’s what makes innovation a step-by-step process. The quote is supposed to signify establishing maps for uncharted areas that allow businesses to continue to expand despite the risks—NOT that you don’t have the resources nor the variables planned to do so (which is the very thing a lot were misinterpreting on). Basically, don’t limit yourself to what you can exceed if you shouldn’t have to, and take the opportunities given.

The drama centers around a group of youthful entrepreneurs who have that similar journey of naivety and innocence, begrudging struggles, fleeting accomplishments, damning reality—you name it. They experience upon trail and error to get to their endgame. That’s really all what this drama is about.
