Police arrested a woman Monday for killing her pornography addict boyfriend Monday in Gyerim-dong, Gwangju.
Kang, 51, gave the 51-year-old Chung a powdered sleeping pill-laced makgeolli, and smothered him to death with briquette smoke, according to the Gwangju Dongbu Police.
Kang said she has long complained that "Chung watches too much porn," police investigators said.
The couple has been living together for over 10 years, and repeatedly fought over Chung's such habit.
Kang told her brother about the murder and he called police.
Police will ask for an arrest warrant after the investigation.
