Books of boy/girl best friends growing up together (from childhood to adulthood)

Hello, I'm looking for novels (or a series or even children/teen books) of boy/girl best friends (as the main characters or in their perspective) growing up together (like meeting as children and are best friends), and I wouldn't mind any romance. I've looked online, and I plan to purchase the following to read:

• Every Summer After by Carley Fortune

• Suddenly Forbidden by Ella Fields

• Leo (Signs of Love) by Mia Sheridan

Also, think of series like “Flash Forward” (old Disney series), without the other “best friends” those characters had.
