Being a college sophomore definitely didn't help Nattawin to realize how important it is to survive. All he did was skipping classes, smoking cigarettes and dogdging questions when people asked about his studies. After the death of his grandmother, his world turned grey and he believed that there's nothing more to look forward to including pursuing his studies.

But everything changed when he met Mr. Rome. The big boss of the Romsaithong Empire who suddenly out of nowhere, became Nattawin's black card.
