Mad for Each Other

On a rainy day, Lee Min-kyung and Noh Hwi-oh experience a series of increasingly unpleasant encounters, unaware they live next door to each other.

At the police station, Min-kyung and Hwi-oh go at each other's throats. Later, Hwi-oh is advised to stay away from people who trigger his anger.

Bumping into an old coworker dredges up painful memories for Min-kyung. With a flasher on the loose, Hwi-oh is roped into patrolling the neighborhood.

Min-kyung is determined to find her missing dog. Getting wind of drug dealing activity on a chatting app, Hwi-oh sets out on an undercover mission.

The flasher resurfaces, this time in front of Min-kyung, but thankfully Hwi-oh is close by. The next day, she asks him for a favor.

Hwi-oh trains Min-kyung in the basics of self-defense. But soon, Min-kyung's anxiety returns in full force with the arrival of a sudden piece of mail.
