In Between Seasons

Hyo-jin is a 32-year-old woman. Two years ago, her husband died in an accident. Her husband has a 16-year-old son, Jong-wook, from a previous marriage. Hyo-jin begins to live with Jong-wook.

One day, three siblings receive a postcard from their mother who left them a long time ago. But all it says is "I miss you." Three siblings are disconcerted by the sudden contact, but eventually, they go on a trip to meet their mother.

While their mother is away from home, the two young sisters are intrigued by the post-it that their mother put in front of the refrigerator.
