**Chapter 1: A Day in the Life of Temptation**

The sun had barely risen over the Italian horizon, casting a warm glow over the quiet streets of Rome. Belladonna Esposito, a mischievous succubus with a penchant for trouble, was already up and about, hovering outside Haruki Hayashi's small apartment. She leaned against the windowpane, her dark brown siren eyes gleaming with excitement as she watched the priest-to-be sleep. "Buon giorno, bello!" Bella chimed, her Italian accent thick and husky, as she tapped on the windowpane. "Rise and shine, sleepyhead!" Her little dark pink horns twitched with amusement, and her skinny, long dark pink tail swished behind her, adorned with an upside-down heart at the end. Haru groggily opened his eyes, rubbing the sleep from them as he sat up in bed. He was used to Bella's antics by now, but it didn't make them any easier to deal with. The 25-year-old priest-to-be had moved to Italy to serve the Lord, but it seemed like the devil himself had taken up residence in his life. Bella chuckled, a throaty, seductive sound, as Haru ignored her and swung his legs over the side of the bed. "You know, Haru, you're so boring in the mornings," she said, her voice dripping with sarcasm. "Don't you ever think about getting out of bed and... you know, living a little?" Haru stood up, stretching his tall frame, and began to get ready for the day. He carefully avoided looking at Bella, who was still leaning against the windowpane, watching him with an impish grin. He had learned to tune her out, to pretend she wasn't there, but it was a delicate balancing act. As he dressed, Bella continued to tease him, making silly faces and gestures, trying to get a rise out of him. Haru kept his eyes fixed on the mirror, adjusting his collar and smoothing his short black hair, his dark brown monolid eyes avoiding hers. Bella sighed, blowing a raspberry in his direction, but Haru didn't flinch. "Today's going to be a lovely day, isn't it?" Bella said, floating into the room, her cheetah-print bikini top and dull dark blue mini denim shorts a stark contrast to Haru's simple, priestly attire. She was a vision in chaos, her short, curly dark brown hair bouncing as she moved. Haru ignored her, heading to the kitchen to make some coffee. Bella followed him, chattering away about nothing in particular, just to keep him on his toes. "So, Haru, what's on the agenda for today? More prayers and hymns, I presume?" The young priest winced, his eyes closing in a mixture of frustration and resignation. He'd grown accustomed to her presence, but it didn't mean he had to like it. As Haru made his coffee, Bella snickered, "You know, I've been thinking... maybe I'll try to tempt you with some nice Italian pastries today?" She winked at him, her full lips curling into a sly smile. Haru shook his head, taking a sip of his coffee. "You're not going to give up, are you, Bella?" The succubus pouted, "What's the fun in that? You're so much more interesting when you're trying to resist me." Haru's expression remained stoic, but a hint of amusement danced in his eyes. "I'll try to keep that in mind." With a flick of her tail, Bella vanished, only to reappear on Haru's shoulder, her breath tickling his ear. "Hey, don't think you're getting out of this that easily. I'll be with you every step of the way, Haru." The priest sighed, rubbing his temples. It was going to be one of those days. His Bible, which he always carried with him, seemed to be a comforting presence, a reminder of his faith and his duties. As he headed out the door, Bella fluttered after him, her voice rising in a teasing chant, "Haru, Haru, you're so boring! Wake up, sleepyhead, and live a little!"
