Knowing the artist, I have a feeling this particular page is going to be heartbreaking.

But I can't get over how cute her little pink socks are

Edit: I was right :(

An extra dimension of depression for you.

The words used in the Japanese version of the song are:
do - donatsu (donuts)
re - remon (lemon)
mi - minna (everyone)
fa - faito (fight)
so - sora (sky)
ra (la) - rappa (trumpet)
shi (ti) - shiawase (happiness)

Note that each panel is related to the word she sings in it: an empty room for 'everyone', a rainy day for 'sky'. ('Fight' has a different meaning in Japanese: saying 'faito' is an exhortation similar to 'be brave', 'do your best'.)

She also doesn't sing the last word.
