Kang Yun-chan is ready for the adventure of a lifetime! Armed with a decent grasp of Japanese and a daring spirit, he sets off on a solo journey to explore new places and meet new faces. Every street is a thrill, every corner an opportunity. But his trip takes an unexpected turn when he crosses paths with three stunning, mysterious young women—completely out of their element and in need of help. When Yun-chan steps in and saves the day, they thank him with an invitation to a secluded, traditional ryokan deep in the countryside. Do they truly just want to say thank you, or could there be even more in store?
