Mercury rules 5th and 8th house is in 7th house in Leo

Mercury is the planet of communication, intellect, and analysis, while the 7th house represents partnerships, marriage, and relationships. When Mercury is placed in the 7th house, it indicates that communication is essential for success in relationships, and the individual may also possess strong analytical abilities when it comes to dealing with others.

However, Leo is a fire sign that adds a strong dose of ego and pride to the placement of Mercury. This can make the native more confident and assertive in their communication, which can be both a positive and negative influence on relationships. On one hand, they may be charming and persuasive communicators, able to win over others with ease. On the other hand, they may come across as arrogant or stubborn at times, which can be a challenge in partnerships.

Overall, this placement suggests that the native is highly analytical when it comes to relationships and may often overthink things. It is important for them to balance their ego and pride and maintain open and honest communication with their partners.
