Both planets here move quickly — Mercury and Sun change position between people born weeks apart. That makes this aspect genuinely specific to the two charts rather than to a generation, which is true of only 59.9% of the combinations people look up.
What these two planets are doing
Sun
The core identity — what a person is when nothing is being performed.At 90° the question this pairing raises is whether conversation flows or constantly needs translating, set against whether each is comfortable being seen as they actually are. A square puts those two demands at odds rather than in agreement, which is why this aspect is read as work rather than ease.
Mercury moves at about the same rate as sun, so the faster one sets how long the exact angle holds.
