Nee Sensei is a very stereotyped yaoi manga. a relationship between a teacher and a student, nothing new. but not because that isn't good enought to read. The story is simple and predictable but have some details that make it cute and interesting in some points. The art is very well done and the author cared a lot about the details of the enviroment and the chracters in general. In general is very cute and all yaoi-fans will enjoy it to the end.
