Off The Charts | Choi Yeonjun FF

When TXT's manager casually invites his little sister to have lunch at the Big Hit Music building, it seems like a simple, harmless visit. She only plans to wait for her brother, eat together, and maybe catch a glimpse of the busy world behind the scenes of one of the biggest entertainment companies. However, things quickly take an unexpected turn. While waiting alone in the building, her presence begins to attract attention, and staff members and security start to misunderstand why she is there.

Instead of being welcomed as the manager's younger sister, she is mistaken for an obsessive fan who somehow managed to sneak into the building. Suspicious looks, whispered comments, and cold treatment follow her wherever she goes. The more she tries to explain herself, the worse the situation seems to become, making her look even more like the "crazy fan" they believe her to be.

Lim Nabi never imagined that visiting her brother's workplace would turn into such a chaotic and embarrassing experience. Suddenly caught in a misunderstanding she didn't create, she finds herself navigating awkward encounters, judgmental stares, and unexpected meetings with members of TXT themselves. As the situation spirals into something far more complicated than she expected, Nabi must deal with the consequences of a simple mistake that puts her right in the middle of the idol world.

What begins as an uncomfortable misunderstanding slowly unfolds into a series of surprising interactions, growing tensions, and unexpected connections. For Lee Heyoung, being mistaken as a crazy fan might just be the beginning of a story she never thought she'd be part of.
