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

Getting sick or being hurt and their SO takes care of them

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

Bad acting foreigners being a nuisance or being in awe of the MLs

Someone eating instant noodles 

Having barbeque on the terrace with friends looking over the citynightlights

Mass quantities of alcoholic beverages (or at least MT bottles and bottles as props)

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

 (Yepp...the very first indication of "falling" for someone)

The two leads ML&FL, (after partaking in mass quantities of alcohol), wake up the next morning half-naked in bed in a hotel room

the way mom and dad control that poor adult son or daughter's life
