On February 7, the actor posted a photo via Instagram of himself with the idol stars on a recent trip together. The caption read, "Thank you to the ahjumma who took this photo for us. Now let's all go home."
Despite the dark lighting, the trio posed together overlooking the seas. It seems the stars took the time to enjoy a vacation despite their busy schedules.
Previously, Park Seo Joon and Hyungsik attended BTS' concert last December to show support for their celeb friend.
