I'm saying that The ML must be the one who will Fall inlove first or showing signs like blushing etc. Like The feelings/reaction when you have a crush on someone. (not tsundere )

And Also the fl is not easy to fall most of the female leads are really easy to fall or always the one who fall first and just because the guy are handsome, talented etc. I like those fl who already matured and not so girly and always blushing ಠ,_｣ಠ
