Promise Me – Dead by April
"Mou hitori no boku, why do you have to leave tomorrow?" Yugi covers his face. He's not crying just expressing emotion. "I know why it's just a rhetorical question." He laughs slightly.
"Aibou, know that I don't want to leave. It's just something I have to do." He places a transparent hand over Yugi's. "I will cherish the memories of us sitting on the sofa together watching cheesy soap operas and playing video games and teasing you for making stupid mistakes. You should cherish those instead of the depressing times."
"That doesn't change anything at all, Atem."
The pharaoh sighed. "Yugi, Don't think of tomorrow as our time to say goodbye. Think of it as us saying until later. We will meet again. I'm sure of it. It might take a while, but I know we will. It's the only thing in my heart that will ever matter."
Yugi smiled. "I love you."
