I guess he's going to use the smell to attract customers. I wonder whether he'll put it directly in the burgers, or use it as a topping, or something else.
@Iskarioth I totally get you, I abandoned this manga for a year and was only able to binge read 12 chapters when the latest release came out. It's a great story when you read it all at once, but gets kind of tedious when you have to wait for monthly release and you forget what even happened in the last chapter.
