“Terius Behind Me,” a romantic comedy spy drama starring So Ji Sub and Jung In Sun, released a new teaser on September 7.

In contrast to the previous teaser, which has all the airs of some serious action and espionage, the newest teaser gives us a taste of what’s going to happen when rogue spy meets single mom and children.

In the teaser, So Ji Sub (as the rogue black ops agent Kim Bon) sits alone in his apartment, as various scenes of his life as a spy flash before his eyes. Hearing a mysterious sound through the wall, he goes to investigate. Cut to the other side of the wall, and Jung In Sun (as Go Ae Rin) and her children are also doing some investigating of their own of the noises from beyond the wall.

Watch the teaser below!

“Terius Behind Me,” which is set to air on September 26 on MBC, is about a spy in hiding and his neighbor, a single mother, who gets caught up in his spy war.
