This is a binding aspect to be found between lovers. With this aspect, a mutual attraction is present. However, the Moon person may find the Sun person insensitive and overbearing, while the Sun person may find the Moon person overly dependent and overly sensitive. The Moon person may feel the Sun person stomps all over their feelings, and the Sun person may not even be aware of this! Regardless, oppositions in synastry are complementary.
This aspect is more problematic than the opposition. The Moon person may find the Sun person overly rational, dictatorial, and selfish, while the Sun person may find the Moon person overly sensitive and emotional. Attraction to one another is present, but it is not without tension and competitiveness. They find it hard to support one another, because there is a basic misunderstanding over what each person needs.
