>>41625066Talk to them every day or two for a month or so then ask if they want to watch a movie or play a game or something over voice chat then spend a month or two doing that once or twice a week then ask if they want to make the whole dating thing official/exclusive then depending on where they live start meeting up in person regularly or at nijifes/other cons and do physical stuff there.
To be honest I'm not sure about going all the way on a first physical meeting if it's at a con we both had to fly to since I'd feel like she would be pressured to not say no if I made a move due to money reasons but we could either talk about it ahead of time or I could try to make a move on the last night since she'd be more likely to do what she actually wants then.
If we've been together for a year or two I'd consider trying to find a job in her country and moving. Though my preference would be to have her move here or have us both move to Japan..
