Former team K member Hayano Kaoru debuted as a soloist?

WHEN DID THIS HAPPEN!! I've read about everywhere now and I didn't hear about when it happened! How come i've never seen her single though? Did she debut yet!?  Everywhere i've read it said she debuted on June 13th so why am I just now hearing about this?

So does anyone know about this?? Please comment and tell me any information i should know because I love Kaorin!!! And I want her single!!
