"Yuuri, why did you tell your sister that those girls will abandon you if your asthma flares up? That's not true at all. Her team members care about your sister's well-being and have even offered to help her in any way they can. It seems like Yuuri wants her sister to depend on her completely, which might create a conflict between them in the future. Although Yuuri loves her sister, she might hold a grudge against her for having to move away because of her sister's condition. It looks like Yuuri is using a twisted form of codependency by making her sister feel like she's the only one who can protect her."
"I have a theory about the first audition round. Do you remember that Yuuri was ranked first and Tsumugi was ranked tenth? And then they ended up in different teams, with Yuu being part of the White Stars and her sister being a member of the Black Stars. Although the teams will change in the future, I think this reflects Yuu's desire for her sister to stand in her shadow, like a shield."
