If you are scheduling a call between Hanoi and Seoul, the overlap window is limited to typical business hours. When it is 9 am in Hanoi it is 11 am in Seoul — a workable window for scheduling. The latest reasonable overlap is around 3 pm in Hanoi (5 pm in Seoul). Outside this window there is effectively no good overlap for regular office hours.
Hanoi and Seoul have a comfortable window for a family call — no awkward alarms required. Hanoi is 2 hours behind Seoul, which gives you about an hour of genuine overlap when both sides are free. Aim for between 6 pm and 7 pm in Hanoi — that lands at 8 pm to 9 pm in Seoul, after the school run and before anyone's ready for bed. For a Sunday catch-up or a midweek check-in, this is the sweet spot.
