I don't think there is any format that inherently "doesn't fall into the category of Fair Use." Fair use is about the nature of the content and how it's used -- how much you used, what purpose you used it for (education/parody/commercial), the effect on the copyrighted work's value, etc. If you, for example, wrote a VN that educated a class, that might include content that falls under Fair Use. I say "might" because Fair Use only applies when you get to court and has to be decided on a case-by-case basis.
Practically speaking, unless your VN gets a lot of attention it's very unlikely it would come to the attention of the copyright owner. Supposing it did, a cease-and-desist letter would probably be their preferred course of action, because it costs them next to nothing (ie. 5 seconds of their lawyers' time) and a lot of people comply. Their next preferred action would be out-of-court settlements; much more costly than letters, but less costly than court. Note that Fair Use
only factors into this if they actually do decide to take you to court and prosecute you for copyright infringement. At that point, you can use Fair Use as a defense and need to prove your use is fair.
In any case, I don't think your use would fall under "Fair Use."
As far as saying something negative about the song, I don't think there's any concern unless they take you to court over the quotation of lyrics and went on to show that in the context of your work, the quote (somehow) lowered the value of the song.
The real question is:

So for example if I have a character sing:
"Hey, I've just met you,
and that is crazy,
but there's my number,
and call me, maybe? "
Would that still be considered Copyright infringement?
Quoting the song verbatim is infringement. With the lyrics slightly changed... I don't know the answer; it might depend on how much is changed, how recognizable it is, etc. If it's worth it to you, then consult a lawyer for advice (I am NOT a lawyer). Whether it "is" or not, nothing stops them from sending a cease-and-desist letter, or even going straight to court. (They're not going to go straight to court. But they
could.)
Another option is to try to actually get permission to use a lyrical excerpt from the song. Find out who the copyright holder/publisher is and contact them. I know it's probably not worth it, because they would probably would want some money for it.

From what I've heard, copyright law is very complicated. So there is nothing to feel bad about.
With all of that being said......If it's really not important to your story, I'd recommend writing you own lyrics. Song lyric quotes may not have much meaning to those who haven't heard the song. It could be a fictional pop song with lines that may actually have some specific relevance to your story (foreshadowing, mood, etc).
