IMO all stories have a love story, a good guy, and a bad guy.
Even if there isn't a Harbinger or TIM or Kai Leng.
There will be somebody other than us. That person may be in our team but wants the glory. So they are now the villain in this story.
Even coming of age books have the love story between the character and the best friend, unreciprocated crush, or whatever it may be.
They have the villain of an idea or person they are against.
Every story will have a main character, villain, and love plot by the time it's been written.
Not sure about that, lots of stories are just partial or incomplete for example in history whenever you have a interesting person or character sometimes they end up dying tragically or whatever before you see the full swath of their experience, perhaps not against a big bad but an accidental alliance or something like that, and finally not necessarily even they would indicate their story is one of "good" and "bad."
In terms of the official "stories and narratives school of tale telling" there is most decidedly an emphasis on the love story good/bad, but the only stories aren't those that are put into books and such.
