Twelve Nyang, Four Chon, Two Chon Eight Pun

Inspector Lee Gyuho is investigating the death of a man who supposedly died from excessive sexual activity.

He becomes suspicious when the details obtained during the criminal's interrogation don't match the results of the autopsy.

Gyuho brings along Jeong Seryang, the village's most notorious womanizer—a man of a similar build to the deceased and someone with considerable experience in the bedroom—and takes him to the crime scene.

He orders the accused to recreate exactly what happened at the time of the incident, using Seryang as his partner.

However, Seryang had naturally assumed that the deceased was a woman. When he discovers that he is expected to reenact the incident with a large, dark-haired man, he is horrified...

“I'm breathing too hard... I—I think my breath is going to stop!”

“Judging by your build, your heart must weigh about twelve nyang, measuring four chon in length and two chon and eight pun in width. Do you really think a heart that sturdy would stop from a single bout of excessive activity?”
