This is all a game of show and tell: you show what you can tell is there.
MC is shown around the same girls, this is a very easy comedy fate mocking dynamic
in many series or movies, where MC who would not face his fears but rather run from them,
like in here, is forced by circumstance to bump into hurdles of the people he is trying to run from: he wants nothing to do with the step sister, he ends up time and time and again
in her neck of the woods no matter who he meets or where he goes.
I don't know who the bad guys are at the college
to reliably point any fingers at anyone else
Then, it is her who is coming to him, but not comiong on to him,
not showering him with kisses, no hugs, no giggles, no happy feels,
she is at his door with no actual peace offering,
she is not proposint anything fresh to do, but actually
asking him to forget and ... nothing, literally nothing, she puts zilch
in the place where all the hurt is supposed to have evaporated from.
How is that ever going to work, if not to mock him?
The fact MC acts neively time and time and again is getting old already,
even in this only second chapter.
The whole plot is MC doing his chores as Sisif and running up that friendship
steep slippery sloapes riddled hill of his adventures.
