Nigeru wa haji daga, yaku ni tatsu

It starts out with the female lead having just finished graduate studies and finding it difficult to land a job. After being let go from a previous employment her father gets her a job cleaning the male leads apartment. When her parents decide to move away she convinces the man to have a contractual marriage so that she can stay there as she did not want to move with her parents. He is very shy and closed off but she manages to get him to open up little by little. He became this way due to his past during his childhood. They eventually have a child and he starts to fall in love with her. She was already in love with him but was ready to give up when he wouldn't open up. Eventually he did. They rode out the pandemic together and in the end he tells her that he wants another child to correct his mistakes from when his first child was born. This is a must watch. At the end of each episode the female lead and the others do their dancing. She's sexy when she dances also the actress that plays her aunt. That was my favorite the ending of each episode. Eventually the male and female lead got married in real life. Now that's a happy ending.
