On this week's episode of Seo In Guk's YouTube series 'Skipping Interlude', the culprits(?) who gave Seo In Guk the nickname "World Gay", singer K.Will and actor Ahn Jae Hyun, appeared as guests.

On this day, the three stars reminisced about the MV that caused a sensation on the internet in 2011, the MV for K.Will's "Please Don't..." which starred Seo In Guk, Ahn Jae Hyun, and SISTAR's Dasom.

Here, Seo In Guk confessed that he was not aware of the "plot twist" of the MV until the very end. He recalled, "I really did not know. The whole time, I thought that I loved Dasom, but that I gave her up for my best friend. And my best friend had no idea. That's what I thought the story was about, but then during the last scene, they told me to rip up the photo, cover Dasom up, and make it so that the two of us are together. That's when I realized, 'Oh, this story is actually about this'. And then I immediately filmed the last sobbing scene." 

Next, K.Will revealed that he plans on releasing a new song soon. He explained, "It's pretty much finished and in the final stages of completion. It's a pretty minor genre though, so while I was talking about it with Jae Hyun, I thought, 'It might be nice to release an MV that picks up the story where 'Please Don't...' left off." 

Hearing this, Seo In Guk turned his back on K.Will while muttering, "What the heck is this man talking about...", while K.Will continued, unbothered, "Jae Hyun said that he's all for it." 

Later on during the episode, the three stars got up to sing the song of the day, "Please Don't...". Halfway through, K.Will announced, "Everyone, a sequel music video is coming." Laughing, Seo In Guk also played along by commenting, "Yes, everyone, please look forward to 'World Gay' Part 2. Please also look forward to K.Will's new album."
