Choi Han-Kyul once again states that he is turning 30 soon, this time he states it's the date after tomorrow. This cannot be true, as he told his grandmother in First Cup that he was 29 almost thirty, then in Fifth Cup he has a birthday, meaning he turned 30. As the series up to this point has only spanned no more than four months (as the coffee shop had a maximum of three months to make a profit, and not long had spanned in the time he met Go Eun Chan and the time he opened the shop) there was no way he could of had two birthdays in that time.
