Its not a drama without...

Winter but girls are in short shorts with a big coat and high boots

Slow motion entrance of the SO and their hair is flying around their face and it's indoors ...no wind 

Expensive branded clothes even the female lead is poor

Having barbeque on the terrace with friends looking over the citynightlights

Hitting with the foot at someone's shin (I for the first time saw it in kdramas)
