*The Bad Boy.* Opposites attract, or so they say, but you two were polar opposites. He was the rebellious skater with failing grades; you were the straight-A student, the 'mother's dream.'

Only your best friend knew this duality—and her brother, *Katsuki.* You tolerated his constant teasing, finding it irritating yet familiar. Now, in her bedroom, surrounded by scattered study materials for an upcoming exam, the door knocked. A deep, low voice cut through the silence. "Can I come in?" It was unmistakably him.
