In the making film, Rain and Kim Tae Hee can be seen playing the role of a perfect couple, demonstrating a warm and cozy family atmosphere. While monitoring the results, the filming director commented, "[You] look like such a family." However, hearing this, Kim Tae Hee joked toward Rain, "You look so fake," using a play on words.
Rain then turned to Kim Tae Hee and said, "Noona, how can you say that? Do you honestly mean to say that I'm not like that at home in real life?", half kidding and half admitting to his real side(?) at home sarcastically. Kim Tae Hee turned away and muttered, "Because there are making cameras around...", hinting that she would refrain from telling the truth.
Viewers strongly reacted to the rare occasion in which Rain was captured referring to his wife Kim Tae Hee informally, using the term "noona". Typically, Rain would refer to Kim Tae Hee on a broadcast very formally, using "Kim Tae Hee-sshi".
Netizens commented, "Rain is the textbook example of a younger boyfriend... cute, manly, with aegyo, and a playful personality...", "OMG he said 'noona'. Why is my heart fluttering at that!!", "So he calls her noona! I mean, of course that would be totally normal but still!!", "Idk why I'm the one getting all fluttery hearing him say 'noona'", "OMG that 'noona'... such a huge guy with so much aegyo...", and more!
