I really need some romance! It can be rich man/poor woman. Or just any drama where the guy really protects the girl. (Movies work too!)
Also it can be any country~

What i've already seen:

Boss and Me
Protect the Boss
Me Too, Flower
Lie to Me
Can you hear my heart?
My Princess
Secret Garden
The Heirs
Master's Sun

Please check out my completed list!! 

Thanks for all the Recs~

Bride of the Century
Down With Love (twdrama, the male lead is not exactly super rich/chaebol but it's a cute drama and there's a «social gap» between the leads)
Star In My Heart (older kdrama)
• Loving, Never Forgetting (Chinese)

• Autumn's Concerto (Taiwanese)

• Easy Fortune Happy Life (Taiwanese)

• Rich Man, Poor Woman (Japanese)

• Tatta Hitotsu no Koi (Japanese)
– The role is reversed though. The woman is rich and the guy is poor. Still good! 
• Goong (Korean) 
– This one is an old drama.
• Fated to Love You (Korean) [remake]
– The original is the Taiwanese 'Fated to Love You'. I've seen both versions. I personally prefered the korean version. I dunno which one you may like though! ^^)>
