Sun square Mars (orb 1.8°) creates concrete friction between the two planets. The orb is very tight; this describes a stable character pattern more than a passing reaction.
Here, Sun in Cancer in House 10 brings identity, ego, father figure, visibility, and direction into House 10 (vocation, status, responsibility, and public image), with Cancer style (memory, protection, belonging, and family sensitivity); Mars in Aries in House 7 brings action, courage, competition, and effort into House 7 (relationship, confrontation, and the mirror of others), with Aries style (initiative, speed, confrontation, and direct action).
Concrete friction: this aspect creates visible tension between ego, father image, and action: will can feel attacked, blocked, or forced to prove strength, sometimes through a weak, absent, inhibiting, or castrating father image. Visible angle: Mars near the Descendant (orb 4.2°) touches an angle; this aspect is easier to notice through direct relationships, partners, opponents, and the way others are met. House 10 (vocation, status, responsibility, and public image) is in friction with House 7 (relationship, confrontation, and the mirror of others); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
