After five years of being by his side, Y/N thought she had learned how to live with it, the quiet, aching kind of love that San never seemed to notice. But things change. San has a girlfriend now. And suddenly, Y/N isn’t the first person he looks for anymore. Not the one he sits next to. Not the one he laughs with. Just… there. So when a night of drinks, laughter, and stupid party games turns into something else when Mingi corners her on the balcony with knowing eyes and a dangerous kind of softness, Y/N doesn’t stop him. Maybe she just wants to forget. Maybe she wants to feel wanted. Or maybe she wants San to finally notice what he’s about to lose.
