Haven't seen Osozaki no Himawari but I guess these might qualify(random order) :
About a group of people : Brother Beat, A Gentleman's Dignity, Ex-Girlfriend Club, Bad Family, King2Hearts, Love Shuffle
Everyday life : Pride, Engine(& other KimuTaku series), Kimi wa Petto, Last Scandal, Dal Ja's Spring, Couple or Trouble, In Time With You, Marriage, Not Dating, My Name is Kim Sam Soon, My Princess, Prosecutor Princess,9 End 2 Outs, Bad Couple, etc.
this is all I could think off, although I've seen a lot that might be what you're looking for.
