After her husband was laid off and began recklessly spending the family savings, tensions rose as her father-in-law harshly blamed his son, while the daughter-in-law could do nothing but argue. Then suddenly, her husband died in a traffic accident. Overcome with shock, the father-in-law fell gravely ill. To care for him, the daughter-in-law started feeding him orally, giving him drinks mouth-to-mouth and spooning him congee. Gradually, their caregiving turned into passionate kissing, savoring each other's saliva and the taste of their tongues. Eventually, in the very room where her husband's altar stood, they sank into a deeply taboo sexual relationship. Caresses, intercourse, blowjob, kissing—despite the husband watching from heaven, their bond deepened uncontrollably. At this crossroads of sacrilegious love and guilt, a new emotion began to bloom.
