Kdrama recommendations for group of friends growing up together?

Preferably in school rather than college, I’ve watched and enjoyed Reply 1988, 1997, go ahead, lovely us, a love so beautiful. I have watched a bit of, and not enjoyed school: 2013, love alarm. I really like the ones where they focus on family as well as their friendship. And also where they grow up as neighbours and fight a lot but are also very close and end with a couple being formed. And I like the ones where they’re set in the past, not modern ones with phones and social media etc.
