I liked the romance & the main leads, the second leads and many misc characters as well. The OST was also okay. I liked it that they didn't overdo the triangle in this one. The reason why it's not 10/10 is because the surrounding story is just not very interesting. This whole delivery business vs. big evil corp thing was extremely typical & for the most part boring and 50%+ of the drama was about this. Other reviewers mentioned that they could empathize with the problems that these youths had to face in "helljoseon", but I found many of these outlandish and unfathomable, it's a bit too much drama logics for me. It's not really slice life, but fantasy, which is fine, but they tried to sell it as slice of life.. The ending was also a bit unsatisfying & although it was a happy ending, it was extremely rushed.

For comparison's sake SooBin's most recent drama "Where Stars Land" is very similar in structure & the level of the comedy & flaws in general are also similar, but the life at the Inchineon Airport was WAY more interesting, I liked that show a lot more for that reason.
