The confusion and the hilarity of the comments is too damn high!
Yea, waifu 11 and big bad guy both realized they fucked up.
Anyways, thx for the translation.
Btw, I think big bad guy just referred to himself and said he is going on a journey, and appointed random housekeeper the new head of the family. All this so he can get away from our MC.
Well, this is just based on cliches and not any actual translation.
