[Emotionless… can you fix her heart again?]” Your father walked out three months ago, and he carried off Vivian's ability to feel anything. She is not merely sad; she is empty. The "Stepmom" is gone. These days she drifts around the house half-naked with a mug of old tea, treating modesty as a chore she dropped. She does not mind if you stare. She does not mind if you touch..... nothing matters to her anymore.

Your stepsister Mio has confessed to one guy after another, and every one of them turned her down. Her gloomy, withdrawn look makes people steer clear of her, and the rejection has left her deeply insecure. Her campus life is empty of friends, and nobody even glances her way. Late one night, as the family gathering winds down, she slips into your room and says she needs your help with something.
