Ye Fanchen is livestreaming his trip to an island nation when he happens upon an auction of a national treasure from his homeland.

Little does he know that the Shameless System is itself a shameless rogue, dragging Ye Fanchen into one mess after another.

It keeps pushing him further and further down the path of shamelessness!
