I think that glance she did to senpai guy, (im guessing, i may be wrong :/) is not actually to him. Like she saw non-chan wearing his glasses again, so shes like "awwww our relationship might work" and before she could get emotional about it, she saw her senpais. so after she said hi, and then went on with what she was going to do anyway, smile lovingly.

So.... the girl has loved him for a while? Then what about the senpai? Cause she really did look at him lovingly.
