"Donovan. We work together," he introduced without any offer of a hand while glancing past Kyu-Sik's shoulder to see if Mi-Ho was perhaps home, unaware of how showing up uninvited could come off to a possessive older brother. Very tall brother, which wasn't intimidating but contradicted his impression that Asians were generally shorter. But then Mi-Ho was nearly his height, long-limbed and flowy in a way that made her seem more ghost-like. Not that he was very tall himself, with very little care to compensate for it. His shoulders remained modestly slumped, hands shoved in his jacket pockets.
Frowning in thought, Donovan hoped it wasn't too obvious that he'd been staring at the other man's features and studying them for similarities with his sister. Their eyes were different in shape, but there was something innate, cold and still but flickering, behind them that made it quite believable they were related. Something that put Donovan at ease in their presence despite an ignored faint ringing of warning. "I wasn't sure if she'd be home," he admitted, but then supposed she didn't really have to be.
