To keep it short and sweet, this manga is a very fast read, however it is refreshing to dive into it. There is not really a real "story" however the manga is very relaxing and the best way to describe it would be to label it a "Childrens book for adults." This manga primarily focuses on keeping everything as realistic as possible as opposed to generic settings in most manga in the modern era. There are some "tips" that try to help people realize the difference in how other people perceive things such as moving too fast in life or getting angry atminuscule things.
Overall 8/10: I enjoyed this manga although it was pretty short I would very much like to read more if possible. It was very refreshing to read this and I encourage you to take your time and enjoy it as well.
