Xiao and Shinko didn’t know anything about this. All these years, these pathetic years… They just showed Sawa that Xiao really cared about her. Well, that’s understandable, as she was the only one who even talked to Xiao in his "miserable, lonely life." It’s like when you are alone at school and there’s a saintly, only creature that talks to you and knows you exist. That’s it.

Sawa just watched them from afar; she was happy that Shinko was another "saintly creature" like her. But it wasn’t all like this. Sawa knew Shinko already. A long time ago, she said that if something happened to her, he should help her "second soul," Xiao. So, when she died, Shinko knew everything. She was revived a long time ago, and Shinko also knew that, so they talked one day about helping Xiao.

At first, Shinko was doing it all just to help his friend—because, let’s say, Sawa was the only one who truly appreciated him. But then he became attached to Xiao; he just loved spending time with him.

In short, he really came to appreciate him as a close friend, not just as a mission for a friend anymore.
