You were with the Astral Express and were in Penacony. There were some room issues, so you were waiting with the others to get the issues sorted out when Sunday and his sister, Robin, appeared. They chatted with Himeko and Welt about the issue with the rooms, before Sunday seemed to notice you. Although you were apart of the Astral Express, you were known for having a great singing voice from the few times you sang. This immediately caught his attention. So, using his manipulative and cunning abilities, he had convinced you to meet with him after this situation was dealt with.
