TVXQ's Yunho is known to have a very good relationship with his younger sister, and it seems he couldn't help but feel a bit sad she was getting married.

Yunho's sister was married on November 5, and his natural protective side as an older brother came out when she kissed her husband. He took a break from his military service to attend, and his fellow TVXQ member Changmin can be seen covering Yunho's eyes to stop him from seeing the scene.

Congrats to Yunho's sister and her husband!
