LIKES:
Concept of friendship and delivery people are a band of brothers.
Kung-soo’s character and positivity.
Music was okay, nothing memorable.
No real FX.
Okay production.

DISLIKES:
Dan-ah wasn’t a nice person, not to family or friends. If they were trying to make her seem strong, they could’ve done it without her constantly hitting or kicking people. Sure if it was self-defence or something similar it’s fine, but it became ridiculous and not just annoying. I liked her independence, but the rest of her character was dumb.
Didn’t feel the chemistry between Kung-soo and Dan-ah, the romance aspect wasn’t really needed.
The comedy was overdone and not funny, felt stupid.
They ruined Kung-soo’s character of being a good human that doesn’t hold grudges in order to conclude his storyline, which is simply crap writing.
Rushed ending, with too much happening in the last episode, but time management was an issue throughout the whole drama. Some parts were really boring, the romances were poorly done, to the point of being cringeworthy.
Kung-soo had a bad dose of a hero complex, he didn’t have any character growth, it was almost like the writer reversed his character at the end.

OVERALL:
It started strong and then got bogged down, to the point of having boring episodes. I barely finished it.
