Adachi tries to ask Shimamura if she'd like to hang out on Christmas, but has a very hard time getting the words out. Meanwhile, Shimamura wonders why Adachi's been acting so weird lately.
Must be nice. Probably never experienced
stiff shoulders back then.
Damals hatten wir noch keine Ahnung,
was verspannte Schultern sind.
Debe ser lindo. Probablemente nunca tuve
los hombros tiesos en ese entonces.
Debe de ser genial. Creo que entonces 
no tenía los hombros tan rígidos.
C’est dingue…
Che bello all'epoca non sapere
 cosa significasse avere pesi sulle spalle.
Deve ter sido bom.
Não tínhamos tensão nos ombros lá atrás.
Вот это да…
