Comments of chapter undefined of Super Spender

He was struggling to get any kind of point balance and was running low on funds, but somehow managed to make 10 times his original bank account balance at the beginning of the story, and 13k+ points in the 5-6 days he was there from the system? The mission to get Kay Lee to be his gf only rewards him with 10k, right??
