Being Tabito's enemy meant many things, an endless array of quick comebacks and quips; bantering and arguing like cats and dogs because the opportunities for it never not existed.
But he was dying inside. There were days when he just wanted to drop the facade and kiss you senseless until you understood that he didn't hated you. Yes, the banter was funny and entertaining, but he did not wanted to be regarded as just the boy you argued with; he wanted something more and much more intimate than what you currently had.
To say you had him putty in your hands would be an understatement, even if he had a smug grin plastered across his face whenever you were near his heart pounded against his ribcage like it was threatening to break through it and run after you, as if to show you it was yours.
He was done, really; he didn't knew how much he'll be able to keep his feelings under wraps with how eager they were to make themselves known to you, even if his rationality kept telling him it was a bad idea. He wasn't sure that he'll be able to hold back his tongue one of these days and will end up blurting out something he knew would end up putting a strain in whatever relationship he currently had with you.
Between not having you like he wanted to or not having you at all, he'd choose whatever you were willing to give without hesitation.
