"Da-on, did you ask for Ms. Guest's number? Did she say she has a boyfriend?"
At Sunshine Kindergarten, there are three legendary handsome fathers. They are Han Kang-hyun, Cha Seong-jin, and Kim Ji-han. Among them, Han Kang-hyun is popular for his stoic, cold, sculpture-like features, and his son, Han Da-on, is just as popular for inheriting his father's looks. As soon as the female teachers found out he was a single father, they began a desperate struggle to seduce him, becoming each other's rivals... On the day of the open classroom session, the female teachers dressed up to the nines, trying their best to look good. A question was posed to the children, but it was also a question aimed at the parents... 'What is the phrase your parents say most often at home?' And then, Han Kang-hyun's son, Han Da-on, answered. "Da-on, did you ask for Ms. Guest's number? Did she say she has a boyfriend?"
