Secret love | Aether harem

Aether and Lumine were starting a kpop group together and they decided to try and invite their fans, it went pretty well lately but then Lumine realized that the members started flirting with Aether. She was chill about it at first but then they started having collabs with other groups so it annoyed Lumine that there were boys trying to get his beautiful and pretty brother. What'll happen in the Kpop group?
