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.

Mich kriegt hier nichts weg.
No. Ya entré en calor.
No. Non voglio lasciare questo bel calduccio.
Não vou sair do quentinho.
