Do you know the drama with the age difference between the main characters?

I want them to fall in love.  

Something like Goblin or Backstreet Rookie.  

I prefer ML to be older, not like it was in I Can Hear Your Voice.

Daring Women

In addition:

• Somewhere Only We Know
• Marriage contract
• Koi wa Tsuzuku yo Doko Made mo
• You are the best lee soonshin
• Sweet 18
• The Eccentric daughter in law
• The spring day of my life
• Takane to Hana
• Ngao Asoke
• Lrh Ratree
• Kimchee radish Cubes
• Love Song - but FL ended up with SML
• Secondary couple:
  • Find yourself
  • A thound Kisses
  • Tarm Ruk Keun Jai

I think Bring It On, Ghost, Cheese in the trap, Radio Romance had about 2-3 years age difference in their characters. But the the actors-actress age gap definitely is pretty big.
