千万别因为这样成仇了

Can a person's heart really change? The person who used to ask me to lend him money and help him recover his losses, I helped him increase his inventory in one day, but I feel like I harmed him! I think he really believes that I am all-powerful and can always make money. He has started saying he wants to borrow money for me to help him play, offering me 10% of the profits. Now that I think about his previous behavior, I really don't dare to take that 10%. What if something goes wrong? People like him could cause all kinds of problems! So this time, it can only be like this; if I can help, that's good enough. In one day, I earned over 1000u from 500u, but there's really nothing more I can do!
