The photoshoot set looked so great! Haha

The two display a perfectly immersed and professional demeanor in front of the camera. However, as soon as filming breaks, they playfully tease each other, unleashing their real-life best friend chemistry.

In particular, Lee Yeon reveals his special friendship with IU, saying, “I want to go to Ji-eun sunbae’s house right now.” He says he is already a regular customer who has visited IU’s house more than four or five times.
