Pillow Talks, HELP!! Pleasee

[Kiritsuna]

I know that there are more than one pillow talk per character, so I want to know how can I get them, my pillow talks always repeat themselves I've done 6-7 times with Asuna, and only got 2 different, with Leafa 5 times and only got 1, so I'm supposing the same thing will happen tome with the rest of the gals

How in the damn world can I get the rest? Is it random? Does it have to do with the mood they are in? (I mostly do them with "Blissful" or "Romantic"). Getting the intimate mood is pretty hard with some characters, so, is there a way to get the rest of them? (I HAVE THEM AT LV6 RELATIONSHIP)

It's too easy getting into the pillow talks, but I'm sad that I can't get others, if someone can pleaaase help me

P.D: I won't watch videos, it doesn't feel the same unless I do it myself
