I'm sorry. I know it's not easy, but for me, for those I've lost, I've always tired to live a good life. In their memory so that they would never be forgotten.

[And that was not an easy way to live. He knows it, but he feels the need to try to give this girl any advice he could think of to keep moving forward.]

It's all I can do for them now. Make sure they're not forgotten and can live on, even if it's just in my memory.
