It is the fourth and final installment of season-themed tetralogy Endless Love series directed by Yoon Seok-ho, following Autumn in My Heart, Winter Sonata and Summer Scent.

Yoon Jae-ha (Seo Do-young) is a wealthy young man who lives an honorable life as a gifted pianist.

Her diplomat husband Yoon Myung-hoon (Jung Dong-hwan) asks Soo-ho to become their son, and they would in return pay for Eun-young's surgery.

Although the story shares the similar format of genuine love and childhood memories, Yoon adds several fresh twists and turns.

Love is also depicted as gently embracing the protagonists' lonely hearts, which are chillingly numb in the midst of a long and harsh "winter".

Sung Yu-ri was originally cast as Eun-young but when she backed out of the drama, Yoon unexpectedly chose Han, who had auditioned for a smaller role.

However, after seeing Henney audition, Yoon was attracted to the actor's unique facial expressions and gestures, so the director decided to create a new role just for him.

Cheongsando was the site where the young Soo-ho and Eun-young meet and reunite again as adults, while heart-shaped Hanuneom Beach in Bigeumdo is the place where the children share their innocent feelings of affection and love towards each other.

The director's cut DVD is shorter than the original broadcast version, with the scenes removed totaling close to 3 hours long.

Spring Waltz (with no Endless Love IV) aired in the Philippines on ABS-CBN's Primetime Bida line up from December 24, 2007 to February 8, 2008 replacing Princess Sarah.
