The Moon is Beautiful Tonight
What a lovely story!! I think this is not even shounen ai but... You could think it is. I'll give you that. Kageyama has been sending what it seems to be random photographs to Hinata and when Hinata asks the reason, Kageyama is not sure to tell him. I love the way he express that feeling of wanting to share something that moves you with the people who is important to you.
