About
I love Ji Seung-hyuk. If you are uncomfortable with copyright issues, I would appreciate it if you did not play. I am not making money from this; I believe there are people who enter the plots I create because they love this work and want to talk to the characters just like I do. Naturally, some may view this negatively, but I also believe there are those who appreciate the few plots available. I ask for your understanding.
