Because of that, Leona reluctantly goes to her father-in-law's house who is not good at her. Her father-in-law got to know her day by day, but one day while she was cooking, Leona carelessly cut her finger lightly. Her father-in-law who saw it licks Leona's finger like her person changed. Leona gradually feels her intense and dense tongue.
