Umm did you forget that even though the father looks like that he's the boss in a family restaurant?
bruv just read the latest episode and commented something ╮(￣▽￣)╭
Oh no I meant stuff like frozen food or another type of food business separate from their restaurant. It was the first assumption tht came to mind
In this house, father does the cooking, mother does accounting (with stuff in skj entertainment/company) so any food related business ideas most likely come from father. Based on this fact then you can put two and two together easier ヾ(❀╹◡╹)ﾉ~
I bet the business is about the food the mom made, to start a food business of some sort
