Yoroizuka is a classical INTJ (in Myers-Briggs typology): efficient, brutally honest, and bad at interpersonal relations and assessing others' feelings. Her intro scene is a perfect picture of an INTJ at work: she points out her colleague's mistake, loses interest in her immediately, takes over her work and completes it in 1/10th of the time, before her other colleague is done lecturing her -- which she also has zero interest in. The other example is her complete nonchalance to her GF sneaking into her house: she walked in, saw her standing there, immediately figured out what happened, and lost any interest in the situation. From personal experience, I can tell that 90% of her brain power was still engaged with work at that point. Only when her GF proposed the lap pillow did she mentally switch to the here and now because it was a completely new experience for her. Still, a control freak like all INTJs, she completely ignored the possibility of receiving a lap pillow and instead immediately offered her GF one, remaining firmly in control of the situation.
tl;dr Dating INTJs is a heavy risk... but the priiize.
"-Please go out with me."
"-Hell no. ¿Dating a minor? That's crime, don't ever approach me with that idea again"
A year later
"Please go out with me."
"Yeah sure"
Maybe she came of age in that year? Just guessing.
