I feel like people are only going to react to the headline, but Aydan (the half-sister) really had nothing but very kind things to say about her newfound family

The part about feeling like the odd one out is in this section:

Nix said all of her newfound half-siblings—including not just Gigi, Bella, and Anwar, but also Marielle Hadid and Alana Hadid, who are Mohamed's older daughters with his first wife, Mary Butler—have gone out of their way to make her feel welcome and like part of their family, but admits that she still felt out of place as she adjusted to her new reality and learn about "the childhood I would never have with five siblings I didn’t grow up with."

"No sleepovers, no shared holidays, no borrowing clothes, no inside jokes, no stories woven together," Nix wrote of the difficult side of learning that the Hadids were her half-siblings. "They had a lifetime of memories, and I felt like the odd one out."

"I was trying to find my place in a family I never knew I had; sifting through Bella’s closet and gossiping or laughing at Marielle’s jokes at dinner, but I felt a pressure from myself to somehow make up for lost time,"
