Rachel Watson, gazing at the scene with a blank gaze for some time already, rose from her seat with a dejected expression and headed towards the exit. In her front, the cheerfully smiling Neville couldn’t help but don a puzzled expression at her behaviour, faint anxiety starting to creep into his heart.

"I've genuinely enjoyed our time together... But we must part here. I'll cherish these memories forever..."

"Wait, wait, wait."

"... Ow."

Isaac Adler, who was only accustomed to walking away first in a relationship and not the other way around, was extremely taken aback by this situation.
