Book recommendations?

So for reference I’m 17, I mainly read ya books but I was wondering if anyone has some good recommendations of:

boarding school books/general romance (spice is okay but only a little, I prefer to read books that don’t have much spice) or books that give the same vibes as these authors:

-lynn painter, I have read all her books including the non ya ones
-ann liang
-alexandra moody

Thanks!!
