Halla Beom, a tiger, puts on sunglasses and leaves for Jeju Island in search of romance, as if turning his back on the world. Leaving behind things like competition, success, and money from the mainland, Halla Beom discovers an old treasure map on Jeju Island.

What kind of treasure is hidden there? On the sacred island of Jeju, will the Halla tiger be able to find the true treasure it could not find on the mainland?

Halla Beom came to enjoy a leisurely life alone, but while embarking on a treasure hunt, he forms new relationships and encounters with Bonjor, a policeman who guards the Hallabong fruit, and a stone swordsman passed down from ancient times.
