There is a nice tranquil air about this story and development is quite inspirational. Nothing yaoi about it, it is clearly shounen-ai, so it would be good to change the tags.
Sora is the son of a man who attempts to kill him and his two brothers. Sora meets a no-name man who he decides to name "Nagi." Nagi only speaks when necessary and he learns to enjoy life from Sora. Good slow read :) re-read? not really. I think once suffices.
