Sonic the hedgehog, bro doesn't give a fuck about Amy rose, chooses to actively ignore her in most situations. Romance is too slow and boring for him, he wants to spend his days running fast and beating up evil robots.
Papyrus from undertale, dude doesn't even know what romance is, ends up trying to use a book he found at the library to figure out how to date someone, and it fails spectacularly as he has no idea what the book is talking about.
