Smug Murakumo because she buys swimsuits only to buy them.

At least Hatsuyuki uses her gacha waifu.

And Murakumo is wondering what is wrong with Hatsuyuki's sense of monetary values.
Frankly, that's how most the women out there are like.

It's definitely "Goddamn" (1990).

Yep, that's the title.

I love to go a-wandering
Along the mountain track
And as I go, I love to sing
My knapsack on my back !

Val-deri, val-dera
Val-deri, val-dera
Ha, ha, ha, ha, ha, ha
Ha
Val-dera

Can't look up German lyrics, but salutes...
