Cashback Over Crushes (English-dubbed)

Jason gave everything for his dream girl, Mia — only to catch her cheating with a wealthy rival. On the verge of a breakdown, he awakens the Trillion-Dollar Subsidy System, which rewards him with luxury homes and supercars for completing tasks.

He rises from rock bottom, humiliates the cheating woman and her lover, then saves his father by confronting his own cousin, gaining hotel equity and launching his business empire. Along the way, he protects a childhood friend and helps a woman named Sophie, steadily expanding his wealth until he becomes the richest man in Cloudhaven.
