Arrogant, jealous, rich, over protective male- When is well done. Some lakorns go to extremes I don't like those too much.
Wrist grabs followed by a kiss- I love it when the scene is tense and she's leaving and he grans her and kisses her. I like to think that he feels if he loses this opportunity there won't be another one.
Co-habitation- Because these dramas are usually full of alone, bonding time and you can see them falling in love more realistically.
One night stands- But only if the plot that follows is a good one. Who am I kidding? I love skinship.
First love/ meet before- I really like it when the leads have a past together, especially if they meet as children. When is well done, the drama will actually give the feeling of "it was meant to be"
Injury- Because it's usually the way they go back together or show their true feelings for each other.
Accidental kiss- come on we all love that "oops tripped and fell on your mouth" scenes.
Last but not least : SHOWER SCENES!!! omg that Ji Chang Wook scene in The K2 ruined me for life.
I love original stories but cliches are like that familiar homemade food you always go back to, even after trying new dishes.
