How long does it take to feel the effects of a line??

My partner currently lives on an extremely chaotic bundle of my lines - specifically my Pluto IC, Sun MC, Saturn MC, and NN lines, all within a few miles of each other. I visit several times a year and slowly fall more in love with the city lol. I’m really grateful to always have positive experiences here, although I never get to spend more than 10 days and was wondering if that was why.
