My Unfamiliar Family

Eun Hee feels flustered after she runs into Jong Min at her team dinner and does something she normally wouldn’t do. She goes to see Chan Hyuk and dumps all of her emotional baggage on him. Meanwhile, Sang Shik goes missing and the family file a missing persons report. He turns up in a hospital and doesn’t seem to recognize his kids at all.

Jin Sook goes with Sang Shik as he heads down to the Ulsan factory for work. When they get there, a young man named Young Shik appears, leaving both Jin Sook and Sang Shik feeling flustered. Meanwhile, Eun Joo and Eun Hee are shocked by the news that Sang Shik had tried to commit suicide. Later on, Tae Hyung heads to New Zealand for a seminar.

Eun Hee chases the trail of breadcrumbs left by Hyo Seok in order to find Tae Hyung. She ends up in Goheung, but she wonders whether her sad hunch will turn out to be true. Sang Shik lies that his memory is back, but he feels confused when he actually starts remembering bits and pieces of the past.

Eun Hee is surprised and uncomfortable with Ha Ra’s sudden appearance, but she can’t avoid the situation because of Gyung Ok. Jin Sook goes to see Sang Shik who is living out of his truck and sees a new side of him. Meanwhile, Eun Joo struggles to deal with her parents’ issues as well as Tae Hyung, and Eun Hee figures out something that she hopes isn’t true.

Sang Shik declares to his family that he plans to take responsibility for Young Shik and his son and live with them. Hearing this leaves everyone feeling flustered. Meanwhile, Ha Ra meets with Eun Hee again and tells her what happened over the week Gun Joo took off from work. Later, Chan Hyuk gets a call from Eun Joo, asking to meet.

Eun Hee wants to know why Chan Hyuk is angry with her and they end up talking about old misunderstandings and resentments. Meanwhile, what Sang Shik thought was a thoughtful gesture only makes Eun Joo feel that he is treating her differently because she isn’t his biological child. Finally, Sang Shik and Jin Sook meet up for a real date.

Eun Hee gets rid of relics from her past and decides to start fresh, while Jin Sook feels guilty about Eun Joo’s divorce. Meanwhile, Seo Young does some digging to find out about Ji Woo’s long-distance girlfriend, and Ji Woo rejects Chan Hyuk’s offer to become a full-time employee. Later on, Sang Shik goes to the hospital for surgery.

Jin Sook feels angry at her kids for hurting her and decides that she wants to spend some time alone travelling. While she is away, the rest of the family learn how big a void Jin Sook’s absence leaves, but everyone still learns to take care of themselves. After some valuable time apart, the family reunites.
