Lee Joon and Oh Yeon Seo started their 'We Got Married' day off with Lee Joon wanting to take a nap.

The two had been drinking milk on the sofa together, but Lee Joon suddenly announced, "I'm sleepy. It's time for a nap!"

Oh Yeon Seo watched him for a bit, and then quietly said, "Why do you keep suggesting that we go to sleep?" Lee Joon was flustered by her words and protested, "That sounds really weird!" His embarrassment carried over to Oh Yeon Seo, who made excuses that it was Lee Joon's fault.

Although Lee Joon argued back it was hers, in the end he admitted defeat and apologized, saying, "Cool guys are supposed to apologize first". To this, Oh Yeon Seo replied, "You're not supposed to say sorry in love."

The two broke down in embarrassment again after she said the word 'love', causing viewers to laugh at the awkward position they put themselves in.
