Oh dude, seriously, no wonder he was happy. He was buying food 8D.
According to the blog owner, Changmin was spotted in a grocery store buying tuna, crab, cucumber and other stuff. He was wearing a baseball cap (duh we can see =x), orange jacket (duh we can see too XD) and jeans.
He was looking very happy and she (blog owner) mentioned the obvious: Looks like he must be eating a lot and barely goes out.
