Min-ho and Beom decide to raise a new-born puppy together. But Min-ho’s family doesn’t let the puppy live inside the house, so the two make a dog house on the rooftop and name the puppy Beom-min after one syllable from each of their names. Meanwhile, as Yoon-ho has hamburgers with Min-jeong, he is happy to see that Min-jeong is wearing the hairpin he gave her as a gift.
