I went to read the first episodes after seeing this post and I'm not disappointed. The story doesn't go to fast. It is interesting and just slightly unsettling. I don't enjoy feeling inconfortable while I have fun but the author made it just unsettling enough to build an atmosphere, so that's great.
It reminded me of the Kdrama Psychopath Diary except it had a string comedic side that this manhwa don't have but is perfectly fine without.
Thank you for sharing this.
