I am not the ceo fiance

This is a story about a little YouTuber who passed away at age of 20yrs old before making it big in the music industry
yu yan transmigrated in the novel crazy ceo ex -fiance who has the same name as her .
when she opened her eyes she was bombard by too many news that she nearly passed on again
Her supposed parents told her she's not their daughter that she was swapped during birth with their biological daughter who is the female lead and they found out she's not their daughter because of the accident she got from falling from the stairs because their blood didn't match and they had to do a DNA test and it proved she's not their daughter
Her fiance already hated her because she's arrogant and willful because she forced her parents to engage them together
now that she's not their daughter the engagement is null
it now belongs to the rightful daughter of their family
she never worked or saved money and has no true friends because she's kinda a bully ,right now she's thinking about what to do because she can't fake amnesia but she doesn't know anyone and all those enemies

maybe that's why the original owner of the body couldn't take all the shock and her soul left the body

and the female lead foster parents are not her biological parents because they stole the female lead and they are childtraffikers and they were abusive to the female lead,
who are my parents???
what am I supposed to do??
where will I go after been discharged from the hospital?
will the enemies the original soul made kill me because I don't have a backer anymore but I am not even the original owner 😭😭...
should I wait to die or fight for the second chance that i have been given ?
be a superstar that i have always wanted to be ?
but can I survive because even the villain hates me I don't know what the original soul did to him .....someone just kill me I am dying of anxiety here why didn't I transmigrated when she's was enjoying wealth
