Regarding the internet cafe.
— First what type of location is it settled in? How much traffic is there around the area of the garage? And what other businesses are there around? What state is it in? Was it renovated at all before all the equipment was settled inside? Further, since it is the owner's father seeking assistance for his son, would it be possible to directly make proposals to him? For example, if the cafe is in a bad location would finding a different locale be a welcomed proposal?
— How many changes can be made? As in, how much more money can be sunk into this business before the brilliant entrepreneur's father decides to pull the plug on the whole operation? Would finding new, high-end equipment be on the table? How about offering other services?
— It's not like Xingqiu's jealous or anything — but imagine having a father supporting you even if you make questionable choices!
