I have cashback system?

Getting a cashback system just after his girlfriend broke up with him, Mark's originally broken heart was filled with ecstasy. With the cashback system, no matter how much he spent, the money would be returned to him in cash! "Ding! You spent ₱500 to buy sneakers, triggering the cashback system. The ₱500 that was spent was successfully transferred to your bank account. Please check it."
