Though he's been a fairly distant husband so far, Sleepy said his heart skipped a beat because of Lee Kuk Ju. The two went to exercise as a couple, and Sleepy put his all into it. Lee Kuk Ju told producers, "I was afraid he'd get hurt if he was excessive, so I told him not to. Even when I told him not to, he didn't give up, and it made him seem so manly."

Sleepy expressed, "I didn't want to give up in front of her. I thought that it would set the tone for our marriage." After exercise, he put her hand on his chest, which was their first skinship�ever. She commented, "I think it my heart flutter a bit," while Sleepy said, "Lee Kuk Ju was shy and made her hand into a fist," describing it as cute.
