Leonardo had always had insecurities and felt worthless next to his brothers. A series of events send him spiraling into depression and self loathing. As tensions and mistreatment between the brothers continue to rise, a figure watching from the shadows will aim to help Leonardo and rid him of his pain.

And she couldn't decide whether or not if it was for the better. When a certain blue-masked turtle barges his way into her life, Y/n can't help but catch feelings. Y/n, Leo's light in the darkness.

Leo scoffed, his grin never faltering. "You wouldn't." A mischievous grin appears on your lips. "You're right. I wouldn't..." Leo's smirk grows, but little did he know you hadn't finished talking. "Maybe I'll go cuddle Donnie." The red-ear sliders eyes go wide and he raises his eyebrows. "Oh-ho-ho! See that? Right there? That's exactly why your nickname is mischief." •Disclaimer: I do not own Rottmnt•
