"Dating(While dating) "had a winning percentage of 50%,"Engagement(Engaged) "gradually approached, gradually decreased to 25%. And "Marriage Period(Marriage period) ", the winning percentage is zero except for the first part. Does that mean that there are many men who will not be able to raise their heads when married?


Perhaps the word "marriage is a graveyard of life" that is said often refers to this.
