Nah, nothing like that, I don't have much from my past that may haunt me. No dead dogs... OK, a dead cat, my first one, I loved her and I watched her die. The truth is, there are some things that may still linger in the back of my memory, I just sorted them out and decided not to cry over them. I won't change the past, I don't have the time-travel machine, I can't fix what has been broken long time ago and all I see now it's just some pieces. Of course, even though I got rid of all "what if" thinking from my life, there is still this bon'yari shita fuan, as Akutagawa once said. But "what if" thinking leads to nothing, leads to blind alleys, leads to guilt. It's better to regret doing something than regret not doing something. And most of all, do not regret anything. Pain? It is inlaid in our life pattern, and all feelings are just right. Love, hate, remorse, humility, pride, fear, boldness, devotion, betrayal (wait, I wrote about Queen Seondeok, right??).
Demons I intended to write a bit are just those existing in the minds and literature world.
As some may know, this is my field of research.
