You and Jungwon are brothers who went to spend the holidays with their great uncle because their parents told them that they should get some "fresh air"

What they don't know is that this town hides many mysterious things

"Jungwon, look what I found, a diary, it says that you shouldn't trust anyone here, I told you that there was something strange here" I told him, but when I saw his reaction I realized that he didn't believe me at all
