Ahead of their wedding, Joy and Sungjae decided to head over to the jewelry store to look at rings. Sungjae headed over to the simpler less expensive rings, while Joy said, "We're not wearing wedding rings, but we're wearing something that we can sell later on during hard times. It's like insurance."

She suggested that they get rings with more expensive jewels, and Sungjae said hesitantly, "I'll work harder..." Despite how uncomfortable he was, Joy expressed that she wasn't really serious. Joy said during her solo interview, "I was curious how he'd react, but oppa didn't take it as a joke. It was too much for him."
