It's Mother's Day, so Yume and Mizuto go out to buy a gift together. Their mother, Yuni, is overcome with happiness to receive a gift from the two of them. Seeing how happy it made her, Mizuto wonders if it'd be nice to give their parents some time to be newlyweds together. However, there isn't much they can do for them on a high schooler's budget. So Mizuto suggests that he and Yume spend the night somewhere instead.
The grass is always greener 
on the other side, I guess.
.لا نقتنع بما هو في متناولنا كما أظنّ

L'erba del vicino è sempre più verde, suppongo.
Parece que a grama do vizinho
é sempre mais verde.
Что ж, у соседа всегда трава зеленее.
