She's in a bad mood.

"That's good news, but why are you here on your own? Where's Ritsu-nee? I thought you can't go out if you're not with her? What if your father or Ren knows that you're here?"

Aiko is chuckling and shaking her head.

"It's okay, I was with Ritsu-nee but she's still busy with her work so I came here early on my own since I got bored over there."

I cross my arms and sigh.

"But you shouldn't be wandering around the city on your own like this, Aiko. What if some bad guys approached you? I know that you're strong and capable of defending yourself but what if you can't? Ren and your father will be worried and you won't be able to leave on your own ever again."

Aiko is surprised and raises her eyebrows.

"Oh? Is that a concern that I'm hearing?"

I scoff and raise my eyebrow.

"Isn't that obvious? Of course, I'm worried about you, Aiko. I don't want anything bad to happen to you."

Aiko is smiling at me happily but she shaking her head.
