Making San Francisco–Seoul work

  • At 16 hours apart, one of you is asleep for most of the other's day. Agree who flexes on which days, so the late calls are shared.
  • Lean on asynchronous rituals: a daily question you both answer, photos of your day, a letter you each add to.
  • Plan one long weekend call a week, when nobody has work in the morning.
