Trust didn't come easily as a superhero and yet it was unwavering between the two of them. If she really did need someone to show up and save her, she knew that it would be her partner without a doubt.
When they were trapped and needed to detransform, she trusted him to keep his eyes closed just as she trusted herself to as well. Cat Noir had never let her down, and while it may have started off a little rocky, things had gotten better in time.
With every fight, Ladybug came to trust Cat Noir more; with every patrol, she learned to know him better than herself. It was hard to not trust someone when they've been by your side since the beginning and had never let you down. There were moments where things wavered and yet trust in each other pulled them through.
Throughout everything she'd trust him, and somehow over the many months and now the years since they'd met, her trust of her partner just grew. One day, very soon, she'll trust him with her biggest secret ever, and she knew that that trust would never be wasted on him.
Cat Noir would always be by her side through thick and thin, through good and bad, through everything. She trusted him, because how could she not when he'd saved her life so many times, risking his own in the process? He loved her so much and put so much faith and trust in her that she could never doubt his unwavering trust, and she knew better than to doubt her own in him.
Cat Noir earned her trust more and more through every Akuma battle, through every struggle, through every moment where their identities were risked or compromised and yet he'd never let her down. Ladybug knew, with her hand locked around his, that she could trust him with the world and more.
