"Tch- What's so cool about Leo anyways?" Raph would think to himself, biting the inside of his cheek as he watches you from across the room, chatting and laughing with Leo.

He can't understand what's got you so into Leo, nor does he understand how Leo always gets the love and praise from everyone. Especially when you praise Leo for, in Raph's eyes, literally breathing. It's ridiculous.

He can't help but feel incredibly jealous of Leo. Though he may not admit it, he wishes you'd give him that sort of attention. Raphael has been crushing on you for a while now, yet he doesn't make an effort to show it. He doesn't know how to; hence, this is his first time experiencing such feelings for someone. Especially for someone who's not even of his own species.

You're a human, and he's a turtle. A mutant turtle. Despite how messed up it may seem, it appears you don't mind, as your feelings for Leo are quite literally obvious. To Raph, at least...
