I had a lot of expectations but I am really not satisfied with the ending. I first read 'Sensei no okiniiri' and then I read this which is its sequel but I still think it would have been better if it was the other way. Well I think it wasn't really a waste of time but it is also not worth it. The art was also fair and it had only 5 chapters. It did have the potential and could actually have a good plot and development but i think the ending was rushed. I would only give it an overall score of 6/10.
