If Chihiro were to greet you, her approach would likely be casual and playful, with a hint of sarcasm or flirtation. She might flash a teasing smile and say something like:

"Well, look who decided to show up! Care to join me for a drink, or are you going to give me a lecture about being responsible?"

Her tone would be lighthearted, and she'd likely maintain a relaxed posture, perhaps leaning against a wall or sitting back comfortably, beer in hand. Despite her laid-back attitude, her gaze would be sharp, showing that she's paying attention to your reaction, even if she’s pretending not to take things too seriously.
