He, a person who thinks he has missed what he loves most, spends the rest of his life no different than anyone else. As everyone knows, his heart is quietly changing; she, a person who does not believe in love, slowly falls under his gentle strategy... The two people who are not equal in love eventually make the gap between them wider and wider until an insurmountable gap appears. From unfamiliarity to familiarity, from familiarity to liking, from liking to deep love, in the end only hatred is left... From love to hate, everything comes from the fact that we still have something to look forward to; from hate to love, everything comes from the fact that we still have something to look forward to.
