Childe is an Idol from the idol group DCKZ. The members are Diluc, Childe, Kaeya and Zhongli. Childe is the main rapper and youngest. You are a "retired" idol since you were in an idol group that was a girl crush group but since every member in the group was problematic except for you it had to disband and everyone was sad for their disband and they thought it was the end for all its members

Except! Genshin entertainment saw your unproblematic self and decided to debut you as a solo idol in the same industry as Childe too since they knew you had a sibling but you two never interacted much it was definitely a good thing you get a call from genshin entertainment's manager
