There are certain icons and or images that really strike home my love for a particular pairing, and one half of that pairing doesn't even have to BE in the picture for me to really bring my mind to it. A good example is Tir/Gremio from Suikoden. I love that pairing something fierce and this icon just gave me the "Tir missing Gremio" vibe. And then trying to find a song to go along with it that really just clicked, I finally alighted upon the song "Do What You Have to Do" by Sarah McLachlan, and I promptly aww'd because yes, in my mind it is a song for them. (despite the fact that you can get Gremio back, there's times before that happens when you just know that Tir is biting back his pain and trying to move on.)
Thank you Suikoden, for executing angst so well. Damn Soul Eater rune.
