Hirose Hana is a native half Korean raised in Japan, who lost her father at a young age. When her mother remarries and brings her new husband and his son back from Korea with her, Hana is thrilled. She's undeterred when her stepbrother Yun Seo -- who hasn't talked to anyone in years -- completely ignores her, and becomes determined to make him smile. Their parents leave on their honeymoon and leave them and the family hot spring in the care of Hana's aunt, and the two begin to bond over their mutual love of winter. Though they quickly become close, an uncertain Hana can't admit her growing feelings for her stepbrother, and her rejection drives Yun Seo away. When she wakes up one morning to find her aunt has sold the family business and left in the night, Hana finds herself alone and helpless. Two years later, living in Tokyo and still waiting for her stepbrother's return, Hana thinks she spots a familiar face -- but finally meeting Yun Seo again is nothing like she imagined.
Both are dramatic dramas about two people who love each other deeply, but their love is against their own sense of duty and understandings. They try to hide these feelings inside them, sometimes even to erase them. In the end, they hurt themselves.
