Group BEAST's member Yang Yoseob thanked his member Yoon Doojoon.

"Yoondoo, thank you for coming as my friend. I had so much fun. Now let's go back safely and prepare for our comeback," posted Yang on his Instagram on Wednesday along with a picture.

In the picture, Yang and Yoon are posing for the camera with sunglasses on- making a straight face. Their hairstyles are similar with both slicked back.

The two had left for Spain recently for the tvN entertainment program "Let's Eat With My Friend," a spin-off program of the tvN drama "Let's Eat 2."
