Well, I have seen female lead falling in love with the guy when she first sees him or at least after couple encounter so want to see opposite of it.
I want to see Male lead falling in with female lead at first sight or couple encounter but very quickly he falls for her; So male lead falls at first sight or couple encounter with female lead.
Female lead should be able to stand up for herself and is headstrong rather than weak who just is a pushover
She should take time to like him back
E.g
Boys over flower and it's versions
Secret Garden
One percent of something
The Greatest Love
