IIRC MC from the manga was kicked out of hes "main" family (or a situation similar to this)
He even made a "side" company that has a name that mean something like "rule over the main family name" if you cut the name in half or something like that....
Anybody know that manga please?

I dont know if it was in the same manga but he went to the army or something and yolo bought building to invest and become rich af but nobody know that
