cdramas where the leads have really good friends?

I'm so tired of watching cdramas where the friends betray the leads (Rush to the Dead Summer, Stairway to Stardom) and I absolutely love cdramas where the friendship makes you all happy inside. Preferably modern and romantic! 

I'm not looking for dramas where they go from friends to lovers, the friendship I'm talking about is like the fl's and ml's roommates in Love O2O, the fl's friends in Skate Into Love, the five fls in Youth, etc etc.

Love is Sweet - FL and ML both have really great friends

Go Ahead - the FL has 3 close friends
