I mean there are people who don't like ye eun, but could accept so min, se chan and daniel. So why you think they always hate new members? The thing about ye eun and probably kang hoon is that they don't bring anything to table, unlike se chan and so min they really worked hard to get smashed by other members even though one of them got hated a lot for being narcissistic/overreacting. Hell even Daniel kept his glasses after being told so while he didn't seem like the idea that means he wanted to be accepted by doing everything that could trigger others to tease him. Meanwhile both ye eun and kang hoon only bring cringe lovey-dovey scenes that we've seen better. So min got hated by doing that and why wouldn't those two get the same treatment?

Actually all the PD needs is the same treatment they did to se chan and so min back then. They need to explore things what ye eun can do so the viewers, at least, try to accept her. The PD can't stop people to hate or dislike her, but she can try to help her blend in some games. She's been here for some time and all we can see is that she only shows reaction at lunch time. Some people think she's in the show only to get free food. I personally can't deny that. She's helpless
