If you do a date at his place, it's 8 hours... I've only gone once so far and that was when I was around 1500~.. The long date wasn't available when I first went over (around 1000~) so I don't know if you have to wait a bit longer... But you can still go on normal dates :)
Hi, I'm Before the dawn on Game Center and I would be so glad if you could send me accessories, especially bracelets and earrings. Also, kim k items :) thanks!!
