On August 22 KST, actor Park Seo Joon took to his Instagram story to thank IU for sending a coffee cart to his current filming set.

Park Seo Joon wrote, "Somin PD, you got paid?", and shared a short video clip capturing the messages IU included on the coffee cart, tagging the singer/actress with a series of fire emojis. Somin PD refers to IU's blue-collar character from the film 'Dream', the first and most recent project that Park Seo Joon and IU worked on together.
