It looks like the final episode is being extended by 10 minutes. I hope they wrap things up well.

'Married Woman Killer' concludes on the 12th at 9:40 PM with its final 14th episode, which was extended by 10 minutes.
I thought Gong Hyo-jin did a great job bringing out the character's personality appropriate for her age group. As a female killer who acts for justice, the story is evaluated as being complete with both genre entertainment and social value. I definitely need to tune in to watch the finale. I hope it wraps up well!
