I would love to hear suggestions for dramas that features the male lead falling for the lead female fast. It doesn't have to be in the first couple episodes, but within the first 4-6 episodes would be great.
I would like the lead male to show deep interest in her by half way through the drama and him actively trying to be with her (even though she might be resisting)...
Something like Secret Garden (... or Heirs), where he pretty much showed how much he liked her at the beginning (like a quick obsession). It didn't take him a while (over half the series) to develop feelings; it was quick.
