Love his personality

I thought we didn't know who the "main" mugo is or if there even is a main, cus logically speaking the first one we see was the older mugo, but the arrogant mugo seems much more in control and prominent throughout the story. Tbh I'm hoping they either fuse into a cocky older mMc. who at times acts childish and has all his memories or somehow they manifest 3 bodies and all date mc.

I call the main mugo the one that's in charge most of the time which is the cocky mugo...not the old one I dont like him he gives me the vibe that he's not trustworthy
