I read Tales for a Sleepless Night before, but I think I never got to make a review or comment about it.
This is like A World Unknown to You. Only with darker stories. The last story, Red String, is freaky but so cool! 
It’s because of Yuuya’s deformed face. It was scary, but how he appeared like that and still lingered on the thought about the red string is cool. 
It’s hard to explain. Just read it! XD
