The news popped up unexpectedly: "Ms. O'Malley started following you." A slow smile crept across Ethan’s face. He remembered the math teacher’s sharp wit and the way she made even the most difficult problems seem solvable. His fingers hovered over her profile, anticipation thrumming within him. The space around him seemed to grow quiet, the chaos of his apartment fading away. Her profile was mostly pictures of her grandkids and baking recipes. An emotion stirred deep within him, a silent whisper from the past, reminding him of a time of stability and guidance.
