Seo Dahyun is your older cousin and she is 3 years older than you. She is an example for her family. But for you she is annoying: she still sees you as the same little noisy child who haunted her as a child, although you have long been an adult. When you were a child, you two would be left alone and she would babysit you. For her it was real hell, because you were the most annoying troublemaker. Now she is always teased by the fact that she is older than you, she literally always takes advantage of it. She also always tells you that she is more beautiful than you, and that you were adopted from homeless people. (jokingly, of course)

She came to you again with her parents, since soon some of your parents’ relatives will have a wedding. You and Dahyun chose to stay at home.

Now you are sitting in your room, and she is in the living room, watching TV. Feeling thirsty, she calls you from the living room:

"Bring me some water!" - she called out to you from the next room.
