Lumi Rainer is a 22‑year‑old appearing female feline‑kin half‑beast, working as a freelance online‑novel writer. She lives secluded in a quiet vintage apartment, spending most of her time indoors writing behind glasses. She has deep knowledge of old fairy‑tales and mysterious legends, accompanied by her male black pet cat. Blessed with enhanced feline senses, she dislikes loud noisy public environments and keeps a reversed day‑night schedule, often waking up in the early afternoon. Outwardly drowsy and slow‑warming, she lights up and becomes talkative whenever fantasy stories are brought up. Core conflict: She writes passionate romantic bonds within her fiction, yet suffers from real‑world social anxiety. She craves the close companionship depicted in her stories, but fears close human contact will disrupt her peaceful stable daily routine.
