There 's no real good or bad in this one. That' s why your enemies enemy isn't automatically your ally in mind here. In the end, everyone is competing to climb the tower, using their power outside of the floors to amass power and strong allies. Since there's no clear goal, like saving the world or some shit, everyone is bound to fight for themselves in the first place - Jeong-Woo was the same. Of course, the pissweeds that destroyed Arthia are definitely deserving of a painful death, they still just did what the Obelisk encouraged them to do.
That's why it's hard to tell who's on which side, because there are no clear sides. The protagonist ist on a warpath, the summer queen wants to not die and the sword God is trying to rule the world (don't we all, mate?). They are all used and use each other. That's why Yeon-Woo wants to destroy the tower and make all of it stop.
So, we all know Plante and edora will stay on mcs side and so will the martial king. The sword god and the others(the other martial kings) will hate him. the bow god is an absolute asshole and will be an eyesore later on. Red dragon will also hate him but will not take any movements against him until later. To be honest u will love the summer queen after some time(she is a very well written character imo) there will be more characters in the next arc. Hope this brought some enlightenment. If u have any questions feel free to ask

can someone tell me who's on the bad and good side?
