On January 11, he uploaded one photo on his Instagram with just one emoticon without saying anything. In the photo, Kangin is seen bending down and gazing straight at the camera while touching his hair with one hand.
Many of his acquaintances left comments such as "Hello" and "Handsome" on Kangin's post that he had posted for the first time in 56 weeks.
Kangin debuted back in 2005 with Super Junior and was active as a singer and actor, appearing in various films and dramas in the past.
Although he showed talent in many fields, he was embroiled in controversies such as assault, DUI, hit-and-run, and non-participation in reserve army training. Eventually, he voluntarily withdrew from Super Junior in 2019.
After leaving the group, Kangin has been self-reflecting without any activities in the entertainment industry. He only updates his personal social media intermittently, keeping fans updated.
