Ms. Emys
Your accurate time of birth is 8:37 PM, as you have mentioned around 8:40 PM. I have taken the time zone as GMT+1hr.
As the way of asking the question indicates that you are fair in dealings, but secretive in nature. If you are aroused, you will flare up. Generally you are a peace monger. Your 1st cusp sub lord Mercury confirm this.
Your 7th cusp (spouse) sub lord Ketu is conjoined with Mars (lord of 5th-intimacy, pleasurable pursuits) in the 7th house. Ketu is signifying Saturn (7th lord – marriage) in 10th house (his place of residence) and Moon conjoined with Venus (lord of 11th house – friends) in 4th house (your place of residence). Ketu is signifying Saturn through Rahu (in 1st house).
So the boy comes from the place, which is the place of residence of both, who is already known to you. You may have some interest in him (5th house).
I assume that the marriage would be in Saturn dasa-Saturn bhukti-Jupiter antara which is from 8-3-2026 to 1-8-2026. (Change in dates because of correction of time for 3 mts).
You may come into contact with the person between 24-9-2025 to 8-3-2026>
God bless you.
Good Luck
