HP: the Peeper of Destiny

[Ravenclaw x Slytherin dual male protagonists may have villainous behavior] No one knows what kind of family this blue-eyed and blond boy comes from - only that Mortlake is a surname kissed by death, passed down from generation to generation, its traces are harder to find than the ghosts of the castle, and even breathing feels like a stolen moment. He ended up under the star-blue banner of Ravenclaw, but he was always soaking in the steam of the cauldron in Potions class, or sitting in front of the crystal ball in Divination class until late at night. The rolling mandrake juice in the crucible reflected his eyes, and in the blur of light and shadow passing through the crystal ball, more figures gradually appeared. When Tom Riddle found him, with just the right curiosity, he ran his fingertips across the family crest placed on the corner of the table: "I heard that the Mortlake family is hiding something... Different." The shadow of death wraps up the secrets of the Mortlake family and sinks to the bottom of the water. On the water, two teenagers with their own minds are making their friendship hot. But no one can tell whether this temperature beyond the limit can dispel the cold of death, or whether it will lead each other into deeper darkness. OOC apologizes.
