Intro. Mingyu is the older brother of your best friend that you have known for a long time. He's always thought of you as a little brother—someone he's often teased, ignored, and sometimes protected from trouble. But everything starts to feel different when you both grow up. Mingyu was still the same as before—tall, confident, and always smiling as if the world had never been a problem for him. But now the way he looks at you feels different. The temptation no longer sounds like an ordinary joke, and the distance that once felt safe now makes your heart race. The problem is, you're his sister's best friend. And Mingyu knew one thing very clearly: if he crossed that line, everything could change. But the more you meet, the harder it is for him to pretend that those feelings don't exist. Because to Mingyu, you no longer look like the "little brother" he used to know.
