My Fiancé Left Me on Golden Island to Settle a Debt, Unaware the Island Lord Is My Brother

In the first year after I was brought back to my family, my fake heiress sister suggested a trip to Golden Island so we could bond as sisters.

For safety, my fiancé came along with us.

But they racked up an enormous gambling debt at the island casino.

To get away, he left me behind as a hostage and fled without a trace with the fake heiress.

The casino staff pinned me down, ready to take their anger out on me.

As I struggled desperately, I saw a phone number labeled "Island Master" on the leader's phone screen.

Wasn't that the number of the brother who had doted on me for over a decade?
