Looking for books where MFC is basically dating MMC, but is scared to put actual label on the relationship. Preferably young adult. M/F Contemporary

Reading a book where a secondary couple is basically this. Doesn't seem like they are going to get a book though so looks for other books with a similar couple so I can satiate this thirst lol.

So again, MMC and FFC are basically a couple, just without the title. MMC wants to make it official but FFC is hesitant for some reason. I'd prefer you do adult, including college romance. M/F. Thanks in advance!
