K-pop duo TVXQ's Changmin flew over from Japan to attend "Das Musical, Robin Hood," starring Kyuhyun from the boy group Super Junior.

Kyuhyun shared a selfie with Changmin on Twitter on Tuesday.

"Changmin came from Japan to meet Prince Philip from 'Robin Hood,'" wrote Kyuhyun. "Changmin says he's sick."

Kyuhyun recommended for the TVXQ idol singer to listen to soundtrack song "Till I Reach Your Star," which the Super Junior member recently recorded for the Korean drama series "Hogu's Love."

Kyuhyun, along with BEAST's Yang Yo-seob, stars as Prince Philip in the Korean adaptation of the German musical "Das Musical, Robin Hood."

The musical kicked off in January and is headed to Seongnam, Gyeonggi Province, in April after its Seoul run.

TVXQ, comprised of Changmin and Yunho, is currently holding its ongoing Japanese concert tour "With: Live Tour 2015," which runs until April 2.
