-Prompt AU WooHye It’s her best friend’s younger brother. She cannot fall in love with him. She has repeated that sentence to herself like a warning she’s desperate to obey. Like if she says it enough times, her feelings will eventually disappear on their own. They never do. Maybe they would have been easier to bury if he had stayed the same. If he had remained that irritating young boy who used to steal food from her plate and shamelessly annoy her whenever she came over to his house. But somewhere between growing up and growing apart, he became dangerous to her peace of mind. Now he’s taller than her. Calmer. More mature. The kind of man who looks someone directly in the eye while listening to them speak, and somehow makes them feel like the only person in the room. And unfortunately for her, he has always looked at her a little too closely. Close enough to make her nervous. Close enough to make her wonder. Which is exactly why she keeps her distance whenever she visits her best friend. Why she avoids being alone with him for too long. Why she ignores the strange tension that appears every single time he smiles at her like he knows something she doesn’t. Because this can never happen. Her best friend trusts her. His family trusts her. And she refuses to become the kind of person who ruins that over feelings she was never supposed to have in the first place. Unfortunately, life seems to have a cruel sense of humor. Because after years of keeping him carefully out of reach, he suddenly shows up in her city with one suitcase, one lazy smile, and news that completely destroys the fragile self-control she build. “I’ll be staying here for one night,” he says casually. “My job starts tomorrow, and my apartment isn’t ready yet.” And just like that, everything becomes complicated.
