He is healthy. He is fine. He is doing what he loves, he is where he wished he could be one day.
But that simpering feeling is there. The feeling that churns your stomach. The feeling that makes you want to cry in the middle of a beautiful thing. The feeling that makes you feel the feelings you would not want to.
He is feeling that, tenfold. He is healthy. He is fine. There is nothing wrong, that the eyes can see.
