I'm working on a C-Dram trope bingo. These could also be used as MDL drama tags.  My ideas so far: 

Harem, reverse harem, CEO, Prince. Poor guy who is actually a CEO or a prince, ML being FL childhood friend, leads having met as children (but one somehow doesn't remember it), contract marriage, amnesia, falling off a cliff (usually paired with amnesia), time travel, reincarnation, girl tripping and falling into guys arms, guy slamming the wall next to girls face (this one is dated), misunderstandings (perpetuated by no one willing to communicate), college dorm room the size of an average house, full makeup and perfect hair when waking up, spitting up blood (any c-drama injury causes this. Step on someone’s foot - they spit up blood), parents who died in an accident, ML’s random allergy or phobia to show he’s “flawed” or vulnerable (Despite being handsome, rich, smart, best in the world at whatever his occupation is, speaking nine languages and having six Olympic gold medals), Simp ML, toxic 2FL, stalker 2ML, toxic mother, kind grandmother, kind but not very bright father, overbearing chairman father…what am I missing?

Disturb the leads when things are heating up 

ML and FL ending up staying together somehow or other (renting same apartment/contract marriage)

FL in trouble, ML being savior

FL speaking up for ML causing ML to view FL differently 

Feeding blood as cure 

CPR kiss 

Huge bandages for small wounds , white powder for all wounds

ML secretly helping FL, even if they have broken up 

Love tokens 

Hairpins as weapon or romantic gift 

People cutting their own neck with sword for honour/as sacrifice to prevent ML or FL humiliating themselves 

Leads family has been framed and massacred and they are the only surviving member now their only goal is revenge and proving their clan was innocent
