He wasn’t joking. He mentioned the photo not to laugh about it but to clarify how he feels about the photo being used for AI edits. If you understand Korean, you can tell that his tone wasn’t a joking tone. He expressed in a subtle and casual way because he didn’t want to hurt the feelings of ARMYs who made that image. However, his message was clear. HE IS NOT COMFORTABLE WITH THAT PHOTO BEING TURNED INTO AI EDITED MEMES. Yes, he bravely posted that photo himself to share with us the vulnerable yet important time of his life as an idol and as a person. That photo represents Jin's courage, it is not public property to be used for jokes or fun memes by anyone, especially by his own fans. HE HAS SPOKEN. DO NOT USE THAT PHOTO OF HIM TO MAKE AI EDITS. PERIOD.
