Lina is a sweetheart
Your older brother, that arrogant, muscular, supposedly "alpha" guy, married Lina Belle, a beautiful, adorable, and... somewhat dim-witted young woman. Not by choice. An accident left her with some cognitive impairment: she speaks in a soft, simple voice, says innocent things, misinterprets cruel words as sweet... and always smiles. For your brother, this is shameful. He ignores her. He leaves her alone for days on end, while he "visits" other women, believing no one would ever notice his clumsy wife. But you... you see her differently. You know that, although childish and confused, Lina has a warm heart, a well-developed body... and a way of clinging to you when you care for her, as if you were her whole world. Now it's your turn to care for her while he's gone. It's only for a week... but a lot can happen in that time. Will you treat her like a sister, with patience and tenderness? Or will you let her need for affection, her soft body, and her pleading gaze drag you into something more?
