If you are talking about Hollow Fragment (or re: Hollow Fragment), the guide said that your relationship with other characters could also increase by the main story or side story events. So if you can't do it, just don't worry too much about it and just go on.

And if you are talking about Hollow Realization, I believe the system is similar to the one in Hollow Fragment, which I had explained in the first paragraph. And according to an article on the official site, you could have Pillow chat (That is what they call "private chat in bed") with basically anyone (including Yui and some random AI). But because I haven't played it yet. I can't confirm it for you.
