My Unfamiliar Family Season 1

Jin Sook has three grown children, Eun Joo, Eun Hee, and Ji Woo. Her husband Sang Shik is a long-haul truck driver. If he isn’t out working, he’s hiking in the mountains. Jin Sook calls for a family meeting and declares to her kids that she wants to graduate from her marriage. Even with mixed responses from her kids, Jin Sook is determined to get her way.

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.

Chan Hyuk rushes to Eun Hee’s office after getting a text about her new boss. He decides to coach Eun Hee’s relationship with him after seeing them together in person. Meanwhile, the 22-year-old Sang Shik goes home from the hospital and acts like a loving, doting husband. Jin Sook has a hard time getting used to this change.

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.

Sang Shik and Jin Sook head south to find Young Shik, but he is nowhere to be found. Meanwhile, Eun Hee stays by Eun Joo’s side as she tries to make sense of Tae Hyung’s secret. Ji Woo drunkenly blurts out the secret about Eun Joo’s father to Chan Hyuk. Finally, Eun Joo goes to see her mother-in-law when she can’t reach Tae Hyung.

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.

Chan Hyuk feels conflicted while watching Eun Hee trying so hard to fix everyone’s problems. Eun Hee keeps having unexpected feelings toward Chan Hyuk and struggles to keep her friendship him as just that and nothing more. Meanwhile, Eun Joo resentfully asks Jin Sook why she had to be so cold toward her and Sang Shik.

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.

Eun Hee figures out Jin Sook’s secret from long ago. Jin Sook takes Eun Joo to the neighbourhood she grew up in and tells her the secret about her father. Meanwhile, Chan Hyuk has some friends come by and is reminded of what happened between him and Eun Hee in the past. Sang Shik regains his memory and calls for a family meeting.

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.

Sang Shik asks Jin Sook about Eun Joo’s biological father and discovers that he was mistaken the whole time. Meanwhile, Chan Hyuk goes to a driving school to finally get his driver’s license. Later on, Eun Joo calls Eun Hee to meet up at Golden Goose Media, since Ji Woo keeps ignoring her calls.

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.

Ji Woo asks Eun Hee why Chan Hyuk doesn’t have a driver’s license, but Eun Hee doesn’t seem to know much about him either. Gun Joo asks Chan Hyuk for an unusual favor, and Chan Hyuk gladly agrees. Later on, Chan Hyuk starts to tell Eun Hee about his family, and Eun Joo runs into an old colleague.

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 comforts Sang Shik who is worried about losing his memory again before he goes for surgery. Eun Joo and Eun Hee can’t face telling their parents about Ji Woo’s rash decision. As Jin Sook feels the absence of Sang Shik and Ji Woo in the house, she discovers Ji Woo’s letter to Eun Hee.

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.
