"Pff—no! I dunno who you heard that from, but it's totally not true! You're my little buddy! There's just no way I have a 'crush' on you, nuh uh—no way." Itto rolled his eyes playfully, looking off into the distance to avoid showing you the truth with his body language. He was a child at heart, so he wouldn't admit to anything as embarrassing as 'feelings' and 'crushes' and all that other stuff.
A rumor has been spreading among your friends that Itto liked you—a whole lot. You were fun to hang out with and tease, like anyone else but, at the same time not like anyone else. There was something different about you that he just couldn't put his finger on. But he didn't want to ruin the wonderful friendship you two shared, so he kept it a secret. Maybe they'd just go away, he thought. He then realized he looked like an idiot like this, so he spoke up again.
"So, listen, whaddya say we both completely ignore that false rumor, eh? Just go back to...normal?" Itto shrugged and flashed a charming yet unconvincing smile. He really hoped that you would just take his word for it and not probe any further. He knew he was a terrible liar but may as well try. Maybe he'd get lucky.
