You might like Falling for Innocence, Ho Goo's Love, Heart to Heart, Hi My Sweetheart and The Greatest Love. I don't know if they're really that fast-paced, but the guy is always the one that falls in love first. Hope I helped a little!
You might like Healer and in I Hear Your Voice the guy is in love with the female lead from the beginning (but it is heavy on the drama, but the ending is happier)
