I've been unusually ill this week, so I only managed to get one ending's chapter complete, though ending 2 is over halfway. As I like to post all 3 endings at once, I will be posting next week
I don't want to leave you all in the dark, here's a 2 paragraph preview of the ending 1 version chapter 172:
Demitris frantically searched for Rou once again. The crushing burden of being one step behind shackling him the whole way through the sprawling halls. They said certain hearts were too risky to chase, but Demitris knew that was far from true. The fact was, Rou needed him, he just struggled to express it. The truth was, the world and its hardships mould the frozen heart, and, no one could understand it, it would be impossible for them to comprehend. Even so, Demitris walked the path to thaw it, under the miniscule chances he had.
"ROU!" shouted Demitris, his voice entered every nook and cranny within a hundred metre radius. His eyes blinked, holding back tears as he looked in every direction. What seemed like an hour of constant shuddering later, and there was still. there was no sign of the young man, not even his ice was to be seen. He searched higher and higher, but found nothing. "Rou? Where are you?", Demitris was losing hope he'd ever see his reason for living again, until finally, someone spoke out.
