Explanation.

Marinette asked adrien to go to the school dance in 2 weeks with him and he said yes but later 3 days away from it that same day kagami asked and he said yes and told marinette that kagami is prettier than her and that kagami said that she was ladybug and then marinette was crying and while most of the school was praising her and thanking her for saving them,while her real friends alya,nino,rose,mylene,ivan,max,nathaniel,juleka,alex,kim,sabrina and even chloe.They didn't believe her even one bit.After that marinette saw all the people that helped her and then ran away.In this world celebrities were allowed to wear disguises and so that's what marinette did.They are also allowed to make a fake identity but when they're found out,they must never wear a mask or have a fake id again.Sayuri zoldyck is marinette's real name.(She is not an assasin).While she was running away,she bumped into luka and luka so her state so he comforted her by hugging her and rubbing circles on her back while he was whispering soft words to her.Luka then carried her home bridal style and felt like she was wearing something but didn't ask then when he had dropped her home on her lawn,she kissed him on the lips and he kissed her back and then she smiled and said thank you and he asked her to the dance and she said yes and they both said that it was their first kiss(in the episode of dark cupid he wasn't kissed by her because a lucky charm she had somehow defeated black cupid even without chat noir).luka also wore a mask.Luka's real name is paras asatsu.They both live with their uncles and aunts.So juleka is luka's cousin.Each of their aunts,uncles and cousin knew their real identities.P.S they're both ripped and know martial arts.
