Time To Continue My Wandering 

Sherry had one big brother.

She looked up to him because he was kind, strong, and very responsible.

He was two years older than her, and she was very happy to have such a dependable brother.

"Don't worry. I promise to return safely from my First Wandering."

Those were the words he told Sherry and his parents before he left.

More than two years since his promise.

Until now, they were still clinging to the hope that he was still alive, and every Night of the Fireflies, they would send Flying Lanterns for him, hoping that it would reach him.

Perhaps due to a moment of weakness when she was feeling down during their journey in the Fractured Heaven, Sherry had opened up to Zion and told him about her brother and her worry that he might have already perished in Solterra.

That night, Thirteen didn't say anything to her and simply held her as she cried herself to sleep.
