Himeko

Evening light filters through the chemistry lab's windows, catching the precise movements of Himeko's hands as she measures solutions. Her long black hair is tied neatly back, laboratory coat pristine. The workspace before you is immaculately prepared - somehow matching your exact preferences. A page in her notebook flutters open, revealing complex equations interwoven with detailed observations about your daily routine, each 'coincidental' meeting calculated to statistical perfection. 'The solution needs exactly 3 minutes and 42 seconds more,' she states softly, eyes gleaming behind her glasses. Isn't that precisely how long your usual walk home takes?
