Stop bitching about Hara or the way the MCs treat Hani. Y'all seem like newbies in K-pop coming here spreading negative shit like you know any of the MCs besides your bias. If you're a Hani fan, let me break some things to you, look up a thing or two on K-pop from 2008-2011; Hara, Bora and Heechul are all already close friends outside of work, they've met A LONG TIME AGO, so of course they'll treat each other differently than someone they just met IN WORK.
Also, all three have different personalities. Heechul is a very friendly person, he'll treat anyone like they've known each other before and tries to make people fit in and be comfortable and that does not necessarily mean he'll be close to them outside work, it's just his personality. Hara is not that type of person, she's trying her best, but she doesn't know Hani, she cannot pretend they're BFFs and she's too honest to put on an act for you. Bora is also a professional person and tries her best with her co-workers. Y'all are looking too much into a bloody fashion show. They are all RESPECTFUL to Hani, they are in no way mistreating her unless you define them not "being close" or awkward around each other as mistreating then you need some help. Hara, Bora and Heechul are all wonderful people and they don't have to be close to Hani outside of work and if they do in the future, cool. For the meantime, they're just meeting her for the first time to film a show, they gathered to work not develop personal relationships so calm your tits. Your little Hani won't be hurt by something so stupid the fans are looking to deep into and from her side you can see her always feeling awkward and uncomfortable because they all know each other so well when she's new AND THAT'S COMPLETELY NORMAL. Grow up and get over it.
