This seems like a clear reference to Everybody. The previous set of pictures also reminded me a lot of The Story of Light photoshoots. I wonder if they are all supposed to reference different points in Taemin's career.

Hi Taemin, I live in USA. SHINee and you were one of the first k-pop groups I discovered when I found k-pop music. Now I listen to more k-pop than American pop music. I'm always looking out for new song's by you. Perhaps someday I can go to one of your concerts if Covid will go away. Stay healthy and record more songs. Also, can't wait till SHINee gets back together and I can hear all of you. Hopefully soon. Tell Key, Hello and Onew and Minho.
