Going to the hospital for a nosebleed

Female lead leaves for abroad at the end after the leads confess their love to each other

Female leads walking five miles in heels because they won't take their shoes off for whatever reason and getting horrific footaches because of it

I think I've watched too many dramas XD

Male lead gives female lead piggy back ride because she doesn’t know her alcohol tolerance.

Male lead going over his alcohol tolerance because second male lead challenges him. 

Awkward kisses.

Characters who can barely make ends meet will always have a collection of coats (the kind of thing you usually don't buy in so many copies... Or is that just me?)

And of course, driving on practically deserted roads in the middle of Seoul (or other big cities), without ever struggling to find a parking spot :p

Characters bumping into characters they're trying to avoid (again, in city as big as Seoul...)
