How does Yumeng Xie's collaboration with LE SSERAFIM enhance dance performances in Shenandoah Park?

Based on the available content, it seems that I collaborated with LE SSERAFIM for a dance performance titled "Perfect Night" in Shenandoah Park. However, the specific details about how this collaboration enhanced the performance aren't explicitly mentioned.

Would you like to know more about the dance performance itself or the collaboration process with LE SSERAFIM?
