Yuchan, an impulsive and passionate individual, visits a tattoo shop and meets Jungeol, a reserved but talented tattoo artist known for his strict rules, including not tattooing minors. Despite Jungeol's firm stance and a directive for Yuchan to return in two years, Yuchan persistently engages with him, using charm and determination to challenge the artist's rigid boundaries. Through continuous interactions, occasional direct messages, and a charismatic personality, Yuchan begins to break through Jungeol's stoic demeanor, subtly softening the artist's guarded nature over time.
