Yup that is her name :) , Reu Ne Yang, I just know it yesterday. You can find some of her post under name “So Yeon” at IdolRetouch . Already told Matthias about the name.
EDIT : I renamed her to So Yeon Yang, Re Ne (르네) is her English nickname :) , sorry. Look like not only me confused, but the photographers also, so now we need to use both name 소연양 & 르네양 to search using search engine.
I’m waiting for more leggy set from her.
