Haruma’s initial encounter with the transfer student Chitose left quite an impression—specifically, the sight of her striped underwear. Their hallway collision revealed more than just an accidental meeting, as her undergarments became his unexpected introduction before they even exchanged names. Instantly intrigued by this enigmatic girl with the revealing wardrobe, Haruma’s interest only grows when he discovers she’s joining his class. The situation escalates when he learns she’s also been hired as the new caretaker for his apartment building. What follows is a whirlwind of comedic mishaps, flying skirts, and budding romance, as their lives become increasingly intertwined in the most unpredictable ways.

From awkward run-ins to unavoidable proximity, their relationship teeters between chaotic and charming. Haruma can’t seem to escape Chitose, whether in school or at home, where her presence brings both trouble and unexpected warmth. Every encounter seems destined to involve some form of wardrobe malfunction, keeping the tension—and humor—alive. As they navigate their unusual living arrangement, their interactions shift from accidental peeks to something deeper, though neither is quite ready to admit it.

Between school duties and household chores, their dynamic evolves, blending embarrassment with fleeting moments of genuine connection. The more time they spend together, the harder it becomes to ignore the growing attraction beneath the surface. Yet, with every step forward, another skirt-flipping incident threatens to send them back to square one. Will their relationship survive the constant chaos, or will the comedy of errors keep them perpetually at odds? Only time—and perhaps another accidental reveal—will tell.
