Jiro solemnly nodded his head, just once.
Watching as tears welled up in the other man's eyes, and then as he desperately wiped them away once again, just as he had before, the god smiled weakly. "I'm real. I have been watching over you all along, yes. I was never something you just made up," he reassured him. Slowly, he reached his hand out, palm upward, his entire arm shaking, but evidently inviting Kei to touch him once more, to gain proof that he was really right in front of him. For now, his body was sustained, even while weakened as much as he was. He could not afford to vanish, to give up, after coming so far.
The words that Kei had spoken next made the god smile much more brightly than before, lighting up his features in a way that almost made him seem like he wasn't so ill. Simply hearing that the other valued his life, that he was worried for him, made him happy, and relieved. It was rather poetic to hear that the one you were dying for didn't actually want you to die.
Jiro decided to make a risky proposal. There was still the very real possibility that Kei would want to run away, that he would be frightened, and not want to have anything to do with him. Yet, if Jiro gave up now, he was as good as dead, so, in spite of the risks, he had to take the chance. "If you truly don't want me to die, will you promise to do whatever you are able to in order to save me?"
