I looked through his Instagram and saw two pictures of him in a wheelchair one with a text about how he spent Christmas at the hospital. He is currently in the drama Six Flying Dragons but he just disappeared so I guess I know why he did now. But there is nowhere I can find what happened I'm worried but there is no information that I can find does anyone know anything?

Is it an old picture? A couple years ago he got in a car accident and hurt his knee. Maybe it was acting up or something.
