who is the diva at the end, I forgot who the characters were in the first story😭😭

Their daughter I can't remember the names but she is daughter of that beta friend and that blue haired toxic omega who was a violinist ig

Assuming 3rd couple’s kid? (Beta-omega relationship)?

I think she's the daughter of Chowon (the blue haired omega) and Kyungsoo (hyesung's friend) I could me mistake tho cause I can't remember some things as well
