Laying out on the balcony together, neither are able to sleep. Yook Sungjae jokingly calls Joy a baby and starts to hum to her. He explains that when he was little, his grandmother used to sing him lullabies. However, he cracks Joy up when he goes on to say his grandmother would fall asleep first.
Joy then asks him to sing a lullaby to her, and Yook Sungjae obliges, singing the song he performed on “King of Mask Singer.” When he looks down, Joy has fallen asleep on his shoulder.
