let me tell you one thing that eu already know her since trainee and they are so close...if you are forever..You have to know that eu said she and all of her member know well about yena and if yena join them they already welcomed her..so what's the problem..actually when first time i know that yena Will join them after izone disband..i feel like yena Will not suit with their concept and anything..but after watching pd48 i know that yena was so close with yiren and sihyeon..they cried together..i feel like they are family..so please support them if yena joining everglow..not hate just, make sure that you have to know more about them and please stay for everglow
