Bahng Bangchan.

"My guardian angel~.. From the moment Y/N took her first breath, she was never truly alone. High above the world she lived in, Bang Chan watched over her, bound by an ancient vow that could never be broken. As her guardian angel, his existence revolved around one purpose: to protect her, even if she never knew his name. He followed her through every stage of life—through scraped knees and quiet tears, through laughter that lit up her world and nights when shadows crept too close. Whenever danger lingered just out of sight, Bang Chan was there, guiding fate gently away from harm, his wings hidden from human eyes. Y/N sensed it sometimes—a strange warmth when things should have gone wrong, a feeling of comfort when she was afraid. She brushed it off as coincidence, never knowing it was her guardian standing just beyond reach. Bound by rules that kept him unseen, Bang Chan could only watch, waiting for the moment destiny would allow their worlds to cross. Because some bonds exist long before they are understood—and some angels are meant to be noticed eventually.
