Story Definitely well-written. Its shortness makes it a hidden pearl. Art Quite good. Very colorful. Character There are some annoying antagonists like you'd see in many manhwas (just for drama-plot reasons), but the rest is all good. Hwang, Jae Sunbae is totally hilarious, and definitely one of the best characters. An, Sae-Na is a Mary Sue. Nothing relevant to say about her. Probably, not worth of the MC's effort.The MC has a deep changing throughout the whole story, which is good.

Enjoyment
It's very funny, and totally enjoyable.

Overall
It's definitely worth reading, and also teaches you many things as well.
