Uzumaki family has to go out, Himawari wants to bring her panda but Boruto doesn’t allow. B/c he will be the one who has to carry it in the end, it’s embarrassing for a boy to carry such a toy.
Boruto : I know you're tired, and I'm going to end up carrying it.
So I'm saiying, leave it here !
Himawari : I'm taking it !
Boruto : No ! I'm a man. That would be too embarassing for me to carry such a girly thing.
