Most women do not look pretty when they cry. Their eyes puff up and turn red. Their face becomes all splotchy. So fits of tears are rarely attractive. More often they are used with a character the audience already finds sympathetic to generate an emotional response. There is a major exception to this rule. Time to go for the big guns. Show that the Tsundere is a girl after all by having her cry. Occasionally this moment acts as a roadstop, a turning point in which the character starts to slowly become a better person. Sometimes includes Biting the Handkerchief. A Super-Trope to Cry Into Chest.
