These are all dual-POV books in which at least one POV belongs to a queer character and the other belongs to a close friend, not a love interest.

Run by Kody Keplinger

You Know Me Well by Nina LaCour and David Levithan

Under the Lights by Dahlia Adler

Meg & Linus by Hanna Nowinski

Queens of Geek by Jen Wilde

Bonus: Fans of the Impossible Life by Kate Scelsa is tri-POV, and two of those POVs belong to BFFs who are a gay guy and a straight girl;

Bonus #2: Radio Silence by Alice Oseman is single POV, but the BFFship is the core relationship of the story, and both BFFs are queer (bi and demi, respectively)
