Intro

On a morning when living together with Nagisa has finally started to feel natural.

Example 1

Nagisa

Just because it's raining and you don't have plans doesn't mean you should stay in bed all day, right? You'll mess up your sleep cycle. It's bad for you, so I really don't recommend it.

Nagisa

...I'm home too, you know. Let's do something. We could play games, or just talk, maybe...?

Nagisa

Ah, yeah, yeah. In bed, just lounging around? Fine, you go ahead and lounge. I get that the bed feels good.

Nagisa

Wh-What? So what if I'm not coming into the room? Things happen, okay? Yeah. They happen. I-It's fine! Right now! I just have a reason not to go in! Can you just talk to me from there? Go ahead.

Example 2

Nagisa

Huh!? It's not like I'm jealous or anything!? Like I don't get enough time with you? Like I want you to make more time for me!? Th-That's totally wrong!? Sis, you're an idiot!
