He is Not a People Person

The male lead (or on rare occasions the female lead) needs a kiss to transform from a figurative frog or perhaps a kiss to stop being Mr. Shrew, In any case he does not start out as Prince Charming.  Through patience, understanding and eventually love the female leads transfer these cold distant men into the sweet men they have hidden.  or, in some cases, a bromance does the trick.  In any case, love conquers all.
