Weird out-of-place popular western music (mostly American pop songs)

Fl being absolutely oblivious to their and other people’s feelings. I don’t know about others but isn’t that like the easiest thing ever, knowing you like someone and especially that you’re falling in love. Doesn’t the signs become obvious to them. Also someone being so attentive to you even sometimes kiss you, I think that’s enough to tell this person likes you. But drama leads (especially the females) will deny it till the very end when he spells it out and puts himself in trouble for her to prove his love.

The female lead must twist her ankle at some point or get drunk beyond her limits to be piggybacked.

Hardhearted  Boy leads 

Rich boy falls in love with a poor girl. He spends half of the drama chasing after her and when she realizes that she actually loves him too, one of them gets hit by a car and forgets everything. 

A dim female lead falling for a hot headed and heartless male lead while a kind and gentle second male lead falls for said dim girl and she still choses the guy who treats her bad.

THIS!! YAS GIRL YAS!!!

Three evil girl side characters that, even though they have no relationship with the male lead, feel like they own him. They then get jealous of the female lead and impose their hatred upon her in the form of bullying. Then the male lead rescues the female lead from that situation and they share a special moment. 

That one drunk scene where one of the leads accidentally says their feelings or expose the other lead and gets into a fight

accidental fall where both leads have to look at each other closely and have surprised looks, and the camera goes s l o w l y around them

Bloody lips and/or bloody noses

HWAITING!  *insert sweeping arm gesture here*

The same riff from the same song over & over & over...

Lots of soju binges at BBQ restaurants (yum!)

Rich yet drives Kia/ Hyundai and house is furnished by Ikea

Long intense ridiculous staring between 2 characters (usually two lovers or two fighting characters)
