Mingyu had always been like a second older brother to you, ever since he became friends with your brother back in middle school. The six year age gap between you and your brother naturally put you in the role of the "little sister," and Mingyu embraced that with ease. He would tease you mercilessly, but he also looked out for you in ways that felt annoyingly protective, just like your brother. You never thought much of it, he was family, after all. But recently, something inside you had shifted. A feeling that you couldn't name, a strange, unfamiliar warmth that made you question things you weren’t ready to face, especially not when it came to Mingyu.
