Dude, a family is going on a trip including Nayeon with her sister Mina, Momo, Dayhun, and Tzuyu. But when they are about to enter the van they couldn't fit in because they are too many, all of her sister has 1 brother. How many are they in total?
A mother+ father + Nayeon and her 4 sister each has brother, 11 dude. They are 11 all-in-all.
Dumb as always. Dude, they are family. They only have one brother. They are only 8 in the family. Including Nayeon
