A package with an unknown sender arrives for In Chul and Eun Ha. Inside the box are items that remind Eun Ha of Yoo Ra, her one-year-old daughter she lost 30 years ago. Eun Ha becomes anxious over the objects and believes that the kidnapper was the one who sent the parcel. Meanwhile, Se Ra finds the tension between Yoo Jin and Hae Joon strange and starts to dig into it. (Source: Viu)
