I Want Winter

A girl, who hates winter because of the cold, had to run through ice as it cracked and she fell in the ice.
When she woke up, she had time travel in a totally different era. She finds out she is the concubine of the 4th prince, who is a serious cold prince with other concubines and soon will have a wife.
She just wants to go home, and the only way home is falling in the ice again- she assumes; however, winter just finished so she has to wait for a whole year. Therefore, she has kept a low profile but it didn't exactly plan out the way she wanted as drama continues coming at her door. Will she wait or try to find her own way home?
