The MV was filmed in the late summer of 2009 at a hotel resort in
Jeju Island, Korea. It took two days to film the entirety of the music video; one day to film the scenes for the story line, and another to film the stand-in scenes with Zhang singing. The video received a mostly negative response from fans, despite it being Zhang's first starring role since her appearance in "
Y (Why...)". Fans criticized it being merely a slideshow, feeling misled by the MV teaser that was released a week before the full MV. Reflective of the song's lyrics, Zhang stars in the music video alongside
Super Junior member,
Donghae. Together, they portray a couple who is about the break-up. The video starts off with the "sunny days" of the relationship, gradually leading to display the "rainy days" of the relationship after Donghae announces his departure from the relationship. It ends with a bittersweet scene from Zhang's memory when they were at the beach together. ==Track listing==
