Seulgi: This kind of money, that kind of power, I only know how to pursue this kind of thing

< p>Irene: The adults don’t look happy, they really are not happy at all

Joy: Happy things, wonderful things, the world is really a vast place with abundant resources

Wendy :Those money, those powers, we have lost interest for a long time

Irene: I am a little different. I will take practical actions to do whatever I want.

I am distressed and distressed. I will definitely be an adult when I grow up. I will regret it endlessly

Joy: My adventure diary of searching for happiness yesterday, today and tomorrow is a little different because I always believe in the existence of positive energy

I need La La La La La Dream La La La La La La

Joy: The friend I met on the way to school ran towards me as soon as I met her. Come on, hold hands and smile.

Irene: The boys who gathered in small groups to try to play tricks on me, I saw through the prank and everything was fine.

Wendy: Although She likes to nag a lot, but she thinks my daughter is the best mother in the world. Hey hey. In tv, the adults who only know how to quarrel are excluded.

Seulgi: Gradually getting into a better place. Because I am me, happiness is more exciting. The joy is that I have you by my side
