The money part is a probably a mystery that will be solved until next chapter.
But for me The part where he insisted that he took the bus was his way of telling Sangwoo that hes not afraid of him anymore. Like him saying That if he took the bus then that means he took the bus. It doesnt matter if hes telling the truth or not but thats what he wants to go with. He knows sangwoo knows the truth but hes just saying he took the bus in his face as a way to show that hes not afraid anymore
I don’t understand the money part.. why did bum ask to borrow money from the woman and why did he kept insisting he took the bus back..
