"kuroki-san , im not the pure girl you think i am"
I wonder if something like that actually happens later on in the manga , it just so weird how she got involved with tomoko and we never got an idea of what she was actually thinking about her.
The only think i remember her thinking was "maybe kuroki is useless if someone dont put pressure on her".
but there is this other weird thing , she said at some point "now i know you are not the quiet and diligent girl i was thinking you were" wich would be kind of weird since tomoko was well known to be a pervert due to pantsu incident , the dick pics in her phone and the time when she had a perverted face when having a wet dream in class.
Right now the manga ISNT yuri harem , but if asuka happens to say she is in love with tomoko that would make it technically an harem.
