HP Anchor of Time: from Malfoy to the Dark Lord

Lin Chen and Lu Yuan were ordinary college students in the real world. Due to an unexpected dispute, they traveled to the world of "Harry Potter" and became 11-year-old Draco Malfoy and 16-year-old Tom Riddle (the future Voldemort) respectively. The two are in different timelines - Lin Chen is at Hogwarts in 1991, while Lu Yuan is at the Wu Orphanage in 1938. Facing the dislocation of their identities, they must adapt to the impact of their new roles: Lin Chen finds himself being gradually assimilated by Draco's pure-blood arrogance and the family's dark magic tradition, while Lu Yuan is fighting against the dark talent of young Riddle to avoid embarking on the path of making Horcruxes. What's even more troublesome is that they discover that each other's timelines are mysteriously intertwined, allowing them to communicate across time and space through magic items. With the help of the disappearing cabinet and the improved double-sided mirror, the two established a secret connection and agreed to change their destiny together. But as time went by, they found that resisting the influence of the original owner's personality was more difficult than imagined - Lin Chen began to unconsciously discriminate against Muggle-born people, while Lu Yuan became increasingly difficult to resist the temptation of black magic. The only thing that allows them to remain themselves is the bond between them. In the pull of darkness and light, their relationship quietly changes, from allies to each other's only anchor. However, the fate of the wizarding world has already been woven into a web, and their intervention will bring about a greater butterfly effect. As Voldemort's shadow gradually approaches, the two must make a choice: succumb to their fate, or join forces to rewrite the entire history of magic? ——When time travelers become villains, can they change?
