I honestly don't know why MAL took around 4 years to finally add this to the database as it was released onto YouTube back in May 2016, but here we are, and now I can tell you why a 103 second long video performed a lot better than a 13 episode long anime.
The most noticeable difference between this and the anime is the art style, and it's something I prefer a lot more, surprisingly enough. The biggest change has to go to Yu Mi-Ra, as well as the fact that the characters don't look like they have colds. Yu Mi-Ra in my opinion looks 10 times more better looking (and attractive) and should've retained the same character design for the anime (and maybe for some of the other characters). The animation for this is beautiful just like the anime, so I have no problems there.
The music is really decent too. The female singer Younha did a really good job of matching her singing to the visuals and the atmosphere of the video. It's really catchy and there's a full version of the song that you can find on YouTube.
Maybe it's a good thing the mods decided to add this entry after the anime ended, it gives us a really good comparison of the anime and shows us what the end product should've looked like. Overall, this is a solid piece of animation and does a better job representing parts of the webtoon in comparison to the TV show.
A solid 8/10
