Hi Hantoki,
This is a fantastic story. The tone is formal. It suits the story and plot very well. The reader is wondering if the speaker is on his way to becoming a sociopath or if he is already there. They will read to the last word to find out. The plot is straight forward and moves along logically. The story is about a boy who is strangely emotionally disconnected from his family and the world around him. The conflict is well defined. There is no doubt about what is going on here. The characterization is fully developed and believable. The story concentrates on the troubled boy, and he comes across as a real person. There is no dialogue but it is not needed here. The description is detailed and vivid. It puts the reader all the way into the story. The story is well structured and consistent in terms of point of view and tense. Great job.
