So what does that card mean?

...I will explain later. For now please pick the next one.

...This one then...

...! Oh my...

...If that's what you want... Then come to my room tonight...

But what do they mean!?

...Whoa, so you're that kind of person huh...

This would mean... Wait no, we are only experimenting.

I don't really understand what is written on it, but... This and this then...

You just need to look at those cards with signs resembling letters on them, then the explanation paper, then pick out whichever you think suit you.
