I find it funny Asamura saved Ayase from getting run over by a car, due to her own carelessness, but it never plays a role in that whole favour balance calculation relationship of theirs. Surely it should be worth a bunch of breakfasts. She could have died, if she had hit her head, or at least broken bones and internal organs easily enough. For all we know, she might have got transported to another world to become a clueless villainess.
