Books with a similar vibe?

So three of my favorite books are:

Simon Vs the Homo Sapiens Agenda
Leah On The Offbeat
The Sky Blues

I also like Komi Can’t Communicate as a manga series, it’s got kind of similar vibes

They all have that kind of end of high school, moving on, escapism, slice of life vibe that I love, and I’m looking for books with a similar vibe.
(No they don’t need to be gay romance, it’s just a coincidence that almost all of these are gay romance)
