The promise was a heavy one. A difficult one to even try to believe in. Hope was a difficult thing - no matter how much Erwin fell and hurt because of it, he could never let go entirely. There was always something telling him that it might work. This time. Or the next. But he chose to trust in the promise. He would see if there was truth or not in the other boy's words, but he tried to remain hopeful.<br/><br/>And then he frowned.<br/><br/>There was warmth. He was feeling it where he felt the pressure of the other's hand on his. A shiver went through his whole body, and his fingers tightened even more around the hand, afraid to let go, to lose this feeling. His eyes were fixed on their hands joined together, his body shivering with something he could not quite define. Even that little touch, even that little warmth was almost to overwhelming to bear after so long. And yet, he didn't want to let go.<br/><br/>Golden chains, black ink, all tying their hands together and more than that, Erwin suspected. He was mesmerized, the hope he had tried to dismiss coming back, fully. When the lights died, another shiver went through his body, and his fingers tightened again, fear that it hadn't work going through his body. But the patterns in black remained on his wrist, and Seishin didn't release his hand. Erwin frowned at the others words, not really understanding them and not really caring right then. The warmth was gone, and he was left more empty than before. By the words Seishin had spoken, it had worked, and although Erwin was hoping that all feeling would return to him at once, he was just glad at the promise. Which didn't mean he didn't miss the warmth.<br/><br/>Carefully, he allowed Seishin to withdrawn his hand, feeling almost the same by the loss of the pressure as he had for the loss of warmth. He trailed the black ink with the fingers in his other hand, frowning, wondering what they were. And then, Seishin's voice brought him back to reality, and his head snapped up, eyes hurting at the sun.<br/><br/>"Yes..." he whispered. "I... Alright." not the more coherent words, but then, he was feeling everything but right then. He trailed off behind Seishin, not really paying attention to his surrounds, the heartbeat of the human loud in his ears and at the same time calming. A promise.<br/><br/>It was with surprise that, when they finally stopped, Erwin found he was in Seishin's room. He blinked, slowly, feeling kind of stupid but not understanding why he was in there. Sure, after all that, Erwin found himself feeling much closer to the human than before, but he couldn't help but think the other boy would try to keep some kind of distance from him. But truly, he found he didn't exactly care. Not right then, at least.<br/><br/>Erwin was going to reply to Seishin when he told about the futons, probably to say something about how he didn't really need to sleep, at least not right then, but he stopped, eyes widening, certain that if he could, he would be blushing furiously right then. If there was something Erwin had clung to desperately, for many reasons, was his privacy, and to see the other cared little about his own made him feel deeply embarrassed. The vampire twisted on his feet, quickly, averting his eyes from the other and fumbling with the closet door. He could almost feel the faint sensation of his cheeks burning, but he knew it was more in his mind than in his body.<br/><br/>He pretended not to hear what the boy said next, although it was stupid, considering his hearing, and he only turned, a futon and a blanket in each arm, when he heard the steady sound of the other's heart, indicating sleep. He carefully laid everything down, and crawled on the futon, covering himself fully with the blanket, head included.<br/><br/>His mind was racing, and Erwin wasn't sure what to make of it all. And then he remembered he would probably have to tell Akane and Hayate next night.<br/><br/>Growling to himself, Erwin curled into a ball and forced the trance to claim him. He didn't need sleep, but he wouldn't stay awake listening to the heartbeats of the household and let his mind roam free. Not right then, at least.
