This article only represents my personal view of "Harry Potter". The wandering, loneliness, despair and fear of Draco in the later period of the original story gave me a strong sense of redemption, so I created this female character. The heroine's character is very strong. From another perspective, her personality is very similar to Draco's. She is sinister, cold, and has a mean tone. This character is not perfect, nor is she a rigid and decent character, because this affects the rationality of Draco's bond with the heroine. In this setting, there are inevitable wars and disputes, and there are a lot of frictions and collisions in the early stage. In this kind of contact, Draco's distinctive character characteristics - always speaking without restraint, actually made her feel the fluctuations of her own emotions and feelings. Under Draco's warmth, she touched the inner iceberg and opened up her long-closed inner world. She looked directly at the importance of feelings and no longer avoided them, no longer rejected others thousands of miles away. It is this kind of redemption that makes Draco, who should be sobbing in despair, wandering and lonely in the later part of the original work, have someone to accompany him. The heroine redeemed Draco in reverse with such redemption. He no longer stayed up all night in fear, and the Myrtle who accompanied him in the bathroom was no longer there, but a real person with complex emotions and warmth. Until the end of the war, two-way redemption is completed.
