An "unexpected" encounter caused two families to suffer due to their stupid behavior, and the two girls got to know each other.
From the beginning, one was guilty and the other was indifferent, but later the two became the closest family members. The two families were also on guard against each other from the beginning and gradually became a family. During this period, they experienced many experiences that they found difficult to forget and seemed ordinary to others.
