The sun felt warm on Amelia's face as she strolled through the park, a light bounce in her step. Butterflies, she thought, a flutter in her stomach – though not from nerves. She was actually, truly excited. For the first time in ages, she felt like dancing.

A new job, a fresh start, a life finally feeling… right. She'd been wrestling with a stubborn knot of anxiety for years, and now, finally, relief. Today she planned to pick up the final pieces of furniture for her new apartment.

That was when she saw him. Jason. Jason who used to terrorize her on the bus. Jason, looking older, softer, a nametag reading "Dr. Jason Miller, Therapist." Amelia stopped, her breath catching. The world tilted slightly. Then, a slow, wide grin spread across her face.
