Can someone help me identify this cdrama?

Okay, someone help. I watched this cdrama back in 2016, and I can't remember the name. All I remember is that there was a priestess. She was dressed in gold and red (presumably for her wedding). She had fallen in love, which she wasn't supposed to do. The man she loved had rejected her, died, or something that caused her to be grief-stricken. She was dancing in the snow, surrounded by these big rocks, when her hair turned white. So she retreated to a temple and meditated. She was a minor character. Someone, please help. (fortunately, I did gif it)
