Were you

taking pics of me just now?

No!

No!! I'm not taking your pictures to use for any dark purpose!

Your sleeping face was really cute!

So I just thought to take a picture of it and put it in the album...!!

That's it! Honest!

Making up an excuse so desperately like that will only make you sound more suspicious, you know?

But, well...

As long as it's only my pictures, I don't mind even if you use it for your dark purpose...
