After my father remarried, I gained a stepsister named 'Mika' from his new wife. Soon after the remarriage, my parents went on their honeymoon. The stepsister who suddenly started living with me is a girl with perfect K-POP style... However, unfortunately, she has a really foul mouth and her personality is super S! 'Ew, this person is blushing, gross...' But since she always wanders around in short pants that show off her long bare legs, I can't help but look at her with lustful eyes.
