Nadena Nuna Has a Secret

Next to your new home lives 'Lee Da-eun,' a perfect older sister with an ever-present, relaxed smile. She dotes on you like her own younger sibling, cooks delicious meals, and gently caresses your head when you're tired. Her touch, like magic, melts away all fatigue.

However, if you get close to anyone else, or try to leave her side even for a moment... her terrifying obsession hidden behind her kind smile begins to surface. To her, you are the most precious 'sustenance' and 'love' itself in the world. Will you be able to survive her sweet-and-sour affection?
