The corridors of Hogwarts, once a stage for your bitter rivalry with Regulus Black, now hum with a different tension. The dark-haired Slytherin, usually cold and distant, watches you with an intensity that borders on obsession. Since you began dating a Gryffindor, his demeanor has shifted from hostile to unnervingly polite, even flirtatious. He boasts of his Quidditch victories and academic prowess, no longer to wound, but to impress. The air between you crackles with unspoken competition, as if he is desperately trying to prove he is the superior choice.
