Yoon Eun Hye

Is it just me or does anyone else feel like Yoon Eun Hye does not want to participate with the other members to go on show except Mieyon? Most of her recent appearance on show I've have only seen her with Miyeon which is couple yeas back. Recently when all the other 4 members appears on a recent variety show and she should have appear with them. Its not like she have a big project that she is currently active with. Also she did not go to Sim Enjin Wedding last year.

I know that Miyeon is her best friend but feel like there is some odd thing between her and the other members Sim Enjin and Lee Heejin.
