Symbolism

This is the first time in the series where Yashiro has looked out ANY window and reflected on his life without it raining. Quite a few chapters back he thought about the beliefs he'd have to give up to let Domeki in his heart and I was really trying to figure out what the beliefs were and now it hit me. Yashiro didn't think he could be saved and also maybe he doubted that he was worth saving, but Doumeki did it! He saved him. Yashiro has no more excuses for the next time they meet.
