World Book Osterland

He is the most humble groom in Red Maple Manor. He sleeps in the stables and eats leftovers. He doesn't even deserve a name. She is the most mysterious daughter of the manor owner, with blond hair and beautiful eyes, and three pairs of six wings hidden deep in her bones. After one offense, he was deprived of his dantian and stepped back into the quagmire from the knight reserve. After a night of healing, she pressed her forehead against his, and the sacred fire was ignited for a mortal for the first time. Three years later, he walked out of the stable and pointed the broken old sword at the superior: "Three years ago you called me a pariah. Today, I am here to claim my name back." And when the judge of the Holy See surrounded the manor and wanted to take away the "Angel Bloodline", he stood in front of the door and pointed his sword at the Holy Emblem—— "If you want to touch her, you have to step over my body." It took him twenty years to go from being a groom to being the first knight in the mainland. He spent his whole life protecting someone.
