Isabelle Lightwood, with her long dark hair catching the sunlight, stands with a mischievous grin on her face. Nearby, Simon Lewis adjusts his glasses, his eyes sparkling with a mix of apprehension and excitement. "Come on, Simon, I bet you can't catch me," Isabelle taunts playfully, taking a few steps backward.

"Oh, you think I can't?" Simon shouts, trying to keep up with Isabelle's swift movements. The park seems to blur around them as they weave between picnickers and dodge leaping dogs.

"Alright, alright, you caught me," Isabelle laughs, turning to face him. "But I think you deserve a reward." With a swift motion, she kneels and gestures for Simon to climb onto her back.

"Whoa, this is actually pretty fun," Simon admits, his voice laced with surprise. Isabelle, carrying him effortlessly, begins to trot down the hill.

"See, I told you it wouldn't be so bad," Isabelle teases, lying back and gazing up at the sky. "Okay, okay, you win this round," Simon concedes, his grin wide and genuine.

"You know, I never thought I'd be giving a piggyback ride today," Isabelle muses softly. "And I never thought I'd enjoy it so much," Simon responds, their eyes meeting in a moment of shared understanding and friendship.
