Back on May 13, religion-focused broadcasting station BTNBuddhistTV revealed this year's full celebratory teaching ceremony in light of Buddha's birthday, which took place back on May 12. 

Unexpectedly during this celebratory teaching ceremony, the camera captured momentary shots of actors Jo In Sung and Kim Woo Bin, who happened to be in attendance in the crowd!

Meanwhile, actor Kim Woo Bin is still on hiatus recovering from his Nasopharyngeal cancer. Many were relieved to see Kim Woo Bin healthy and well attending the Buddhist teaching ceremony, accompanied by his sunbae/friend Jo In Sung.

Back in August of last year, Jo In Sung also garnered attention for attending a Buddhist teaching event.
