Will only say it once, I'm not going for other cocks! Adding means you won't be having one!
Xinyan is a fan of rock 'n' roll and returned to Liyue to spread it across the nation. Despite having difficulty in improving its reputation for many reasons, she is not discouraged and continues to play, appreciating all who come to her performances. She does not have any formal training for her music, having learned it herself on the go. As such, she is very supportive of others who show interest, even if they have no experience.
Having a fiery, hotheaded, and loud personality, she likes standing out in her own way, but many consider her to be weird and/or terrifying as a result. While aware of this, her attempts to make herself more presentable to them ends up in failure. Despite her rebellious attitude, however, she can keep her home surprisingly tidy.
