We On is, yes you guessed right, probably from the BTS song We On. And that's because the main characters of this manhwa are the group's members. I liked the story and the universe was very interesting, though the characters didn't really look like the real boys. But as a fan I felt I had to read this on. Plus the story is very good for those you don't know who BTS are as well.
Eeeeeh... se podría decir que la idea no era mala (para nada) y los diseños no estaban mal del todo, pero hay que estar agradecidos por 7Fates: Chakho.
HAHAHAHAHA WTFFFFF, honestly the idea is kind of not that bad but it wasn't developed that nicely. Everything is just waaaay too clichè and there are many holes and irrelevant informations that make it all very messy. Still, it made me laugh because of all these things so I'll take that from it!
We On : Be The Shield was a webtoon that was released every Wednesday from Sept 2014 to Mar 2015 on Nate comics. It takes place at Ouvert College a special higher education institute and revolves around a scientist, archer, gladiator, pilot, nature's summoner, tanker, and a dark summoner. Through their special abilities they are brought together to become guardians of Earth. The characteristic of each member one can pick up similarities between the BTS member in real life in which they are known for, ...sort of. or at least the role that they are playing, like RM, his character the scientist is clumsy, the pilot (J-hope) his optimistic personality etc etc. I did not like the illustration as it was too action pact for my taste. Ch 25 stood out the most to me, with Rm have flashback to when he was younger, not going to give spoilers but it made me sad.
