🎨 Kian84 (Owner) – "The raw romanticist who destroys common sense" Features: The mastermind behind all the bizarre rules and interior design of Kian Guesthouse. He completely rejects conventional standards, making guests climb rock walls instead of using doors or creating water slides that combine brushing teeth with doing laundry. Personality: Infinite Positivity & My-Way Attitude: Even when others are horrified and ask "Is this right?", he has the immense grit to push through calmly, saying "It'll work if you just do it." Unfiltered Simplicity: He has a raw personality without any pretense or hypocrisy, serving guests food meant to be eaten with bare hands. Unique Empathy: Though he seems to live haphazardly on the surface, he has a warmth that deeply listens to and comforts the young guests' worries through his own 'Kian-style' perspective.

🐹 Jin (BTS - Main Staff) – "The unexpected fact-bomber, the reliable ace" Features: Despite being a global superstar, he is the 'realistic ace' who works harder than anyone at Kian Guesthouse. He is the practical housekeeper who cleans up Kian84's absurd instructions from the closest range. Personality: Playful Fact-Bomber: Every time Kian84 says something ridiculous, he opens his eyes wide and delivers refreshing direct hits like, *"Hyung, does it make sense to brush your teeth with shampoo water?"* Responsibility & Kindness: A charming tsundere who grumbles but meticulously organizes and looks after the accommodation behind the scenes so guests aren't uncomfortable. Overflowing Variety Sense: He shows an unexpected charm by letting go of his world-star weight and getting swept into Kian84's pace, bickering or ruining his image together.

🐰 Ji Yeeun (New Staff) – "Bouncy human vitamin, unexpected passion character" Features: A source of energy who instantly brightens the potentially dark atmosphere of Kian Guesthouse with her unique, unrivaled voice and lovely charm. Personality: Honest and Lovely Reactions: She evokes empathy from viewers with her realistic 'annoyed' expressions and reactions that she can't hide when seeing the haunted-house visuals of Kian Guesthouse or Kian84's antics. Unexpectedly Passionate: She looks like she might be clumsy or a whiner, but she has a persistent personality, even going as far as obtaining a water leisure license herself to travel to the main building on the sea. Politeness and Sociability: She plays the role of a bridge between Kian84 and Jin perfectly and has excellent sociability, befriending new guests without hesitation.
