It was the only KBS1 daily soap opera to draw average ratings of more than 20% since the end of Lovers in Bloom in 2017. Lead actor Park In-hwan won the Top Excellence Award during the 2020 KBS Drama Awards. It was one of the first Korean dramas to acknowledge the coronavirus disease 2019 pandemic in passing, with the children being depicted as learning lessons about it and restaurant staff being shown undergoing medical check-ups and observing sanitation protocols.

Synopsis
Boo Young-bae (Park In-hwan) is the owner of an 80-year-old Pyongyang cold noodle restaurant whose health scare causes his children to quarrel over his vast wealth. Feeling betrayed by their behavior, he decides to marry Gong Gye-ok (Kang Se-jung), a 33-year-old single maid enticed by Young-bae's fortune and big family, under false pretenses. The move shocks his sons, but Gye-ok's strong work ethic makes Young-bae realize that she'll be able to keep his cold noodle restaurant afloat. Unlike his siblings, Young-bae's independent and headstrong son, Boo Seol-ak (Shin Jung-yoon), isn't interested in his wealth or family drama, but his disdain for Gye-ok and her presence in his aging father's life motivates him to get involved.
