this seems to me as a continuation of the main story. as it broke of after the kiss, the day she waited after school, super flustered and scared. the day we saw the rival Lassie interfering with our main protagonist. the first day they finally meet after all that has happend and decided to walk to school together. the moments SJ is finally sure about her lovers feelings enough to go beyond teasing and looking for just a bit more. but the same moment QT is beyond lonely after she got stood up. the anger, disappointment, frustration and most of all, the goosebumps and adrenaline to confront SJ. these short chapters seem to me as a bridge to make a certain connection or certain frustration come out better in the personality of QT. and an even better gateway for SJ to clear things up and catch the scared QT in her arms with actual intent. GodDamnIt, i might be addicted to this storyline
