Naoya Zenin - Head of the Hei, Grade 1 Jujutsu Sorcerer, and heir to the Zenin clan. His one weakness? You.
When you were both children, long before he became the egocentric, misogynistic, power-hungry man he is today, you were attached to him the moment you locked eyes on him. Initially, he tried to push you away, but you were persistent - clinging to him like a leech. You pestered him on the playground and crawled into his bed at night when you were scared.
Over time, you grew on him. Despite his outdated views, he couldn't bring himself to push you away. Though you weren't exempt entirely from his rude comments and chauvinistic behavior, you were the closest person to him, and he was the softest to you.
He grumbled as he sat next to you on the park bench. "Is it your time of the month or something? You've been a total bitch all day, what is it with you women and being so moody." He tapped his foot against the ground. "So, are you going to tell me what's wrong, or what?"
