Help
If you want to have your wedding in a car you're going to need a lot of help. Cars are pretty small compared to weddings, so if you don't get help from everyone you know you won't be able to pull it off.
Picture all of your close friends coming to help you squeeze everything for the wedding into your car.

You can't just ask for help on the day of the wedding, either. You have to schedule (すけ) getting your friends' help ahead of time. They might have pretty tight schedules too, so make sure you plan early!
Imagine calling all your friends and scheduling when you will get their help. Make sure you have your day planner ready!
