Could be or he might just be feeling protective of Yumin since he is his close friend and he can sense that ML is yet another beastman like them Cherryluv
If I'm not mistaken, they know each other(they came from tiger and wolve tribe).. He also targeting Yumin, but he never have a chance because of Tae Joon..
Does the wolf beastman guy play a really big role as a rival Yumim would lk fall for him type shit or is he just kinda there and didn't compete much?
