In that moment, nothing else mattered. Taiyō's mind worked to block out everything else that was going on around them-- the shouts of civilians wondering what was happening, the rising smoke, all of it. That Tsuki was safe beside him, gripped tightly in his arms, was enough for him. The rest of the worries that would come from the whole situation could wait until later.
When he felt her grip loosen from around his back, he slowly followed suit. He leaned back, swiping his jacket sleeve across his eyes to wipe away the tears. Normally being this close to Tsuki, face-to-face with only a few inches of difference between them, stirred up a rosey-red tint over his cheeks that he couldn't ever refute. Nerves always got the better of him. This was one of the few times he didn't have to face that. Taiyō was too caught up in the moment for those flustered feelings to catch up to him. He listened carefully when Tsuki spoke.
What she asked of him was a heavy oath: a promise not to die before her. Taiyō couldn't reply right away. He found himself staring at the girl before him, the foreign situation leaving him dazed-- normally, he was the weak one in need of Tsuki's strength and assurances. A reversal of fates caught him off-guard. Seeing his hero fatigued from worry, flushed with red cheeks, unable to keep eye contact ... It was almost like looking into a mirror of himself. Now, for once in his life, he could support her, the way that she always did for him.
Truth be told, he didn't think about it. Later on, the weight of his words would come back and press against him, but when Tsuki needed this promise from him, there wasn't a force in the world that was going to stop him. "I'm not going anywhere, Tsuki. Nowhere." He raised his own bony pinky, crossing it against hers. "You've been waiting on me, all of this time. You've been waiting for me to take off running. I ..." Flashes of the confidence and determination that flared up in Tsuki's eyes when she had said appeared before the Hozuki heir.
"I haven't paid you back. And I know, I have a long way to go, but ... Well, that just means I can't die yet, you know? I need to be around to thank you for all you've done." Uncharacteristically, his gaze posed a resolve fitting for his words. Confidence surrounded his slight, gentle smile. The Hozuki's finger wrapped around hers. "That's a promise." Those words hung in the air, lingering while each word took its time to sink in. But then, that was when Taiyō's body moved on its own.
His body leaned in, and he tilted his head slightly back. Taiyō's lips found their way to Tsuki's forehead. Just like that, with a wave of sudden confidence built up throughout the day, he sealed his promise with a kiss.
