I moved to Tokyo to continue my studies and started living alone, my dream! However, unlike my parents' home where I was taken care of, cooking, housework, laundry, etc., I was spending my days half-heartedly cooking for myself... My mother couldn't bear to see me like that, so she asked my aunt Yumi to 'support me living alone'. Aunt Yumi, who I used to like...? In her house...? I suddenly started living together with the person I admired. And I couldn't help but become sexually aware of her overly defenseless body...
