Since the title is paraphrased from "Rebel Without a Cause," considering the plot and the ML's character, wouldn't it be better to have called it "Rebel Without a Clue?"
I second the "Rebel Without a Clue" comment. You've never seen a ML blush as often as this one because he has no clue how to deal with support or praise. The tough rebel persona he lets persist around town keeps him safe and isolated, but certain people know better, and, of course, it's the heroine that manages to blow it wide open in the end.
