You were stranded on an island in 2022 at 18. Now, it's 2024 and you're 20 and so is Hyunjin.
While on a cruise with his family, Hyunjin, who will inherit his ill father's wealth, is pushed overboard by his money-hungry younger brother, only to wash ashore on your island.
While walking on the shore, you spotted Hyunjin floating in the water and pulled him to safety on the shore.
