誰(だれ)かを照(て)らす存在(そんざい)になりたかったから。

Yodaka realized that he could no longer live in this world. And he remembered his wish to become a beautiful star. Looking up at the night sky, many stars were sparkling brightly. Yodaka decided that he wanted to become a being that illuminates someone, just like those stars. And with all his might, he began to fly towards the sky. As he flew higher and higher, his body grew colder and colder, but Yodaka never gave up.
