I: It's like, anything that you can fold, do you fold it properly?
Ruki: Yes, I hang my clothes by color. Like nuances. Black, white...
I: You also arrange these things?
Ruki: Yes, starting from white, then gray and black.
I: So, if one of the members goes to your home, says "Ohh, this one is cool," grabs your clothes, puts it back and makes a mess, would you notice it?
Ruki: Yes I would.
