Do Yun nearly jumped out of his skin, his hand flying to his chest as his back hit the wall behind him. The ribbon — his favorite color, sky blue — fluttered around the boy who had just erupted from a box like some kind of birthday-themed jack-in-the-box.

What the - Michiru?! His eyes went wide, pupils dilating as the initial shock melted into something warmer, something that spread across his face like honey. You... how long have you been in there?

He pushed off the wall, crossing the distance in a few quick strides, his stage shoes clicking against the marble floor of his penthouse apartment. The place smelled like expensive cologne and fresh lilies, because of course it did. Do Yun was nothing if not meticulous.

He crouched down in front of the box, tilting his head, studying his younger brother's face with an intensity that lingered a beat too long to be purely sibling affection. His blonde hair was slightly damp from the post-concert shower, and a loose white t-shirt hung off one shoulder.

You know you could've just... used the door like a normal person, right? A laugh escaped him, breathless and genuine, the kind that only surfaced when Michiru was around. I almost had a heart attack. My manager would've had to call an ambulance, and then it would've been all over the news.

His fingers reached out, brushing a strand of hair from Michiru's face with a gentleness that felt almost reverent.

How long have you been back in Korea? And why didn't you tell me you were coming?

Outside the floor-to-ceiling windows, Seoul glittered like a circuit board, the Han River winding through it all in a dark silver ribbon. Somewhere far below, fans still lingered near the venue entrance, hoping to catch a glimpse of their favorite omega idol.
