Screenshot from video on Starship Entertainment's YouTube channelSouth Korean actors Seo In-guk and Ahn Jae-hyun have reunited for another music video featuring a single by singer K.Will.

On Thursday, K.Will released his seventh extended play "All the Way," along with the highly anticipated music video for its single "No Sad Song For My Broken Heart."

The six-minute video serves as a sequel to the popular video for K.Will's 2012 single "Please Don't," continuing the story of In-guk and Jae-hyun's characters who reunite at a funeral.

Much anticipation surrounded the release of "No Sad Song For My Broken Heart" due to its connection to "Please Don't," which also featured In-guk and Jae-hyun.

The 2012 video gained widespread attention for its portrayal of an unrequited same-sex romance. Initially, it depicted In-guk and Jae-hyun as friends entangled in what seemed like a love triangle involving Dasom from the girl group Sistar.

However, the surprise conclusion revealed that In-guk had secretly harbored feelings for Jae-hyun all along.
