At about 3:20 in the 2nd episode of 5-toubun no Hanayome ∬, Nino and Miku are fighting over the TV.
Do parents in Japan forbid their children from having computers or tablets?
If not, Nino and Miku could just watch their favorite shows in their computers or tablets and there would be no need to argue. But in the 1st episode of Season 1, when Uesugi entered the quintuplets' room, there seems to be no computer in their rooms.
If so, why do the parents do that? Do they think having electronic gadgets would have negative influence on children's study (, which might be consistent with Japanese schools' strict rules)? However, having the internet is a great convenience while studying and can save you much pain when you fail to solve some difficult problems. As a doctor who works in a hospital, the quints' father must have a high degree. It would be unbelievable if he is unaware of that.
So, in the end, why do Nino and Miku need to fight for the TV?
