He didn't like the idea of moving; he had to leave a lot of things and friends behind. When they moved in their new home, Donghae felt homesick and went to take his puppy, Bada, for a walk...

Im Yoona is a girl raised in Seoul. Her mother passed away a month ago and in one random day, she suddenly felt depressed. She missed how her mom used to sing her lullabies at night, she missed her mom's cooking and most of all, she missed her mom's prescence in the house. Her father was away at work and the house got more depressing so she decided to go out for a walk in the park...
