@vTool If I remember correctly, they felt attraction for each other during Spring Break but Araragi was too afraid of involving her after she almost died during the events. Also, it's a common "they never got to tell each other" scenario. If Araragi confessed to her or Hanekawa to him, they probably would have dated, but none of them dared to make the first move and confirm each other's feelings. Senjougahara went right for it though, and like explained in this chapter, Araragi would have said yes if only because he can never say no.
I love how Arararararararagi stalks a loli in a horizontal position whilst casually ignoring the librarian's existence, that made my day
Oops, I stuttered
