"If avoiding desire-driven incidents is too difficult, then release those desires and find ways to fulfill them. Of course, mishandling things might lead to getting 'knifed,' schemed against, or thrown into a battlefield of love—but as long as you survive, there's always a chance to turn things around."

"Be meticulous in your conquests, stay true to your character, leverage every advantage around you—and don't panic when faced with the occasional bad ending."

"Winning hearts is troublesome work, but having a reference target makes it much easier."
