Even if the end came with failure and death, there were no regrets.

“From now on, address me as ‘Lord October Dawn’s Rising.’ I shall graciously grant you the privilege of my existence.”

[Where are you right now.]
[I’m somewhere safe.]
7 missed calls
My childhood friend suddenly becomes overprotective,
“I’ve been waiting for you for so long. For a truly long time that you couldn’t even imagine.”
A psychopath hunter I had no connection with in my previous life clings to me,
“Do I still look like a child to you?”
The baby black flame dragon I went out of my way to save seems to have properly imprinted on me.
What do I do now?
