Mattheo Riddle first met Harmony Cassiopeia Black at six years old, at a high society event. He had attended with the Notts, being taken in as their foster son but treated like anything but family, however he had developed a brother bond with with their son Theodore nott who was the same age as him, Harmony had just been taken in by Walburga & Orion Black, her grandparents, her father Sirius black had been imprisoned for crimes against wizards, Mattheo could relate to the shame that hung on her shoulders, this gave the young girl permission to play with Theodore & Mattheo & her cousin draco Malfoy, so she was forced on them like a parasite or.. a invading queen, Mattheo didn’t understand that day what she would come to mean to him, upon playing with her they learned she wasn’t so bad after all, with curly brown hair to her shoulders & green eyes the color of the forbidden forest, she was fierce & not afraid of getting dirty & to Theodore’s pleasure she was a intellectual who loved to read, to mattheos she was a artist & sketched more beautifully than even him, and Draco finally had a cousin who he could get close too, she was sensitive & it was weird to work around but by the time they were ten years old the four were inseparable, Harmony was the only girl & so unspokenly she was their princess & they had gotten in quite a few fights about her, when they started at Hogwarts they were all placed in Slytherin together & their friendships shifted & inevitably drifted, Mattheo & Theodore were brothers thicker than blood & Draco was prince of slytherin always feuding with Harry Potter, mattheo became king of the school, Theodore was made prefect, Harmony star seeker of the Slytherin quidditch team & top of her class, speaking of Harry potter he was absolutely in love with her, she was his godsister technically & the two of them were childhood friends before the downfall of both their families, he could never make her his though because Mattheo & Harmony had started dating in third year, seemingly the power couple of the school but Harry could see how toxic it really was & so could a lot of other people they’d just never dare say it out loud, Mattheo loved like religion. This was not a known fact, not now in any case, but it was just as undeniable as the fact that the very sky is blue.He loved with complete reverence, and a note on reverence is that it has a great many synonyms. Complete faith, desperation, unabashed wholeness, without room for fault. Reverence, worship, it all meant the same. An inherently flawed belief system. Though, while it was not always so wicked, he loved in a truly unhealthy sense.
