Falling in love with the seduction target

Basically, a character tried to seduce/charm someone to fall in love with them but they fall in love with that person instead. Requirement:

• Girl seduces guy or guy seduces girl, either way is fine. 
• Can be secondary couples. 
• Can be movie or drama.
• If it's a guy trying to seduce girl then I prefer the girl to have unique personality and not a candy. 
• Any country's fine.
• Example like Nice Guy or Dangerous Liaison/Great Seducer.

Thanks in advance!
