In preparation to see Lee Kuk Ju's family, Sleepy gifted her a matching Christmas sweater to wear with him and cleaned up their newlywed home. Lee Kuk Ju's mom brought a freezer box full of food and prepared healthy eats for her son-in-law, who acted cute as she cooked up something delicious for him.

Sleepy even went as far as preparing a special Christmas dining setup as well as presents of a massager, clothes, and hat that he bought unbeknownst to Lee Kuk Ju. Needless to say, Lee Kuk Ju's mom was quite happy with her daughter's onscreen husband.

Later on in the night, Sleepy, Lee Kuk Ju, and her family went to a karaoke room, where they partied it up. Sleepy did his best to entertain, and it was obvious Lee Kuk Ju was touched by his effort.
