@vexelpops the tall girl noticed that the short girl is interested in her and that she’s faking to be working on the 12th floor to spend time with her, so she presses the floor the short one’s working on, showing that she is also interested in her enough that she knows where the short one’s actually working, flustering her
my wording is confusing due to there being only 1 gender pronoun but that’s the best I can explain
