This story takes place in modern times. It isn't some far-fetched fantasy; it's very close to us, unfolding among the people around us. What's more, the protagonist is a post-90s generation youth. These days, it's quite common for couples to break up. But the male protagonist's stubborn devotion, the old-fashioned ideas he holds, his faithfulness in love, and his morally ambiguous nature at the time all combine to cause an enormous uproar.
