i was so confused at the start , it feeled like if it was the real deal and had to look up the name of the author thinking "maybe this is a doujinshi made by the author of the original story":
Till half of the sory it seemed like te manga , then it recalls a lot of stuff from the actual manga and even the phrase of tomoko when senpai finish school.
I liked it but as everyone else , i think this would never happend in the manga.
