Abnormally close best friends who calls each other sweet endearments BEFORE they even get together

Hello! I’ve scoured through similar posts in this subreddit, but haven’t found anything that fits what I’m looking for.

I absolutely live for the oblivious jealousy and possessiveness that comes with this trope, but something about them calling each other “baby” or “sweetheart” or any type of endearment normally used for lovers even before they realize their feelings is just chef’s kiss!

It doesn’t matter to me if they had a hundred lovers before but I’d appreciate if they’re both single and don’t engage in hook ups with others on-page by the time the book starts. It’s okay if mentioned in passing, I guess? I can kinda understand sleeping around if they don’t realize they have feelings for the other yet, but please no descriptions if possible and I’d really like if they don’t sleep with others just for the purpose of making the other MC jealous.

Other no’s include: - SA - cheating - drug abuse - sharing (fine with poly as long as they all end up together) - third act break-up - basically anything too heavy (some light angst that normally comes with this trope is okay-ish)

I’ve read some books with friends to lovers dynamics but I couldn’t for the life of me remember if any of those has what I’m looking for. If they get recommended, I guess I’ll just read them again 🥲

I could be very picky with what I read so I understand if the recs I’d get would be very limited (or none at all) but I figured I’d just try. Thank you!
