I think it's more common in japan for some married couples to sleep separately, since their parents are celebrities they must have hectic work schedules and i think this is one of the reason why couples in japan prefer to sleep on their own, better sleep
Oooooh. I mean I get it because my grandparents had separate rooms, but I just see it as weird having one room with two separate beds. New knowledge though. Haven't seen that before.
Why are there separate beds for the parents?
