It's a Promise, Right...?
This is Karamatsu and Ichimatsu...stuff. It's not dirty. I don't do stuff like that.
This is based off of a song I really like~

Also, always remember that it's very hard to keep in character while writing a song fanfic. Depending on how the images are in the song depend on how the character acts.
Such as in this fiction, Ichimatsu is taken as a very weak and confused human, while Karamatsu is strong and kind, not painful at all.
