Her song "Candle Lights" was used as the ending theme of Japanese dub version of Korean film A Millionaire's First Love.

"Winter Love" debuted at #2 on Oricon Daily Singles Chart, but rose to #1 on its fourth day out.

It landed at #2 on the weekly charts, being kept out of number one by a narrow 3,814 copies.

The single's debut sales and position were very high, compared to her previous single "Key of Heart / Dotch", which had low sales due to poor promotion by her record label, Avex Trax.

It sold double the amount of "Key of Heart / Dotch's" total sales, and outsold "Nanairo no Ashita: Brand New Beat / Your Color".
