While her parents were away on an overseas trip, Soyun was watching adult videos and masturbating at home. Just as her heart began to pound nervously, 'Why stop? It was good.' 'Kyaak!' Someone had broken into her house?! Startled, Soyun freezes, but the dangerous intruder, who seemed to know who she was, brazenly demanded her panties and to perform cunnilingus on her. Flustered and bewildered, she ended up doing erotic things with him and even feeding him. Soyun somehow ends up cohabiting with the man for two weeks while her parents are away…? By the time she realized she was in deep trouble, it was already too late.
