Jieun's pov

I was booking a dining room for our sister-brother relationship announcement. I told yoongi"Brother, Can you call your friends and I will also call mine. I only have four besties. And you?" yoongi said"I only have 7 besties. And I have found a dining room."He showed and we decided to book the one brother took. I called Blackpink our friends group and told them to have dinner at XXXXX hotel with us at 8 pm. And to dress formally. Brother told the same thing to his friends. It was already 6 so I was choosing a dress. Then I finally found one. I got ready in half an hour and looked like this.

While yoongi looked like this.

We just took my brother's car and drove to XXXXX hotel. We had to be there by 7 for the preparations. Till 7:45 everything was ready. I just did a touch of my light makeup as I was sweaty.

Then suddenly the door opened and we saw Blackpink and some other guys. Maybe Yoongi's brother's friends. And I realized that one of them was the one in the jjimjilbang. yoongi introduced them to us and we introduced ourselves to them and suddenly the door opened to reveal a person to the others were in shock.
