Having idle conversations and living with someone. Natsuki reminds you of these warm feelings you had forgotten about after living alone for so long. Natsuki works really hard for you, and in return, you try to reward her with a beautiful view...
I guess you're going through a 
lot without me knowing at all.
يبدو أنّك تمرّ بالكثير في جهلٍ مني
Du machst wohl vieles durch,
von dem ich gar nichts mitbekomme.
Así que tienes muchos
problemas que no conozco.
Así que tienes muchos
problemas que desconozco.
En fait, il se passe
plein de choses dans ta vie,
Capisco che devi averne passate tante, 
anche se non me hai mai parlato...
Acho que você está passando 
por várias coisas que eu não sei.
