The members of Girls' Generation gathered for a meal to celebrate Sooyoung's birthday.

On February 14, Yuri posted a video on her YouTube channel showing the birthday celebration she had with YoonA, Tiffany, and Sooyoung.

On this day, Yuri explained while traveling to the meeting place that the girls decided on a dress code for the birthday party and explained, "Today's dress code is 'ugly' because Sooyoung said that the shops are closed (for the Lunar New Years holidays) so it would be hard for her (to get new clothes)."

Yuri explained, "I searched a lot, and I even considered borrowing clothes from my mom, but it ended up being too much," showing off her outfit.

Wearing a colorful patterned sweater and red checkered pants, Yuri said, "This is the outfit for my solo album performance," adding, "I ended up wearing a stage outfit to someone else's birthday party and Lunar New Year's meal."

Upon arriving at the restaurant, the meeting place, Yuri worriedly laughed, saying, "Is it right to come to a beef restaurant where elders gather wearing stage outfits? It's embarrassing." When she arrived, she explained to Sooyoung that her sweater was her stage outfit, making her laugh. The members were satisfied with YoonA's outfit, who wore the perfect adorable 'Grandma' sweater.

When Tiffany appeared in a plain sweater, the members exclaimed, "How is that an ugly sweater?" Yuri also said, "This is my stage outfit. I'm so embarrassed," causing laughter. 

After the meal, Sooyoung tried to pay, but Tiffany had already paid. Although Sooyoung said she wouldn't accept gifts, she was moved when she found out that the other members had prepared one.

At the end of the video, Yuri shared photos filled with memories with Sooyoung, accompanied by subtitles starting with "Congratulations on the birthday of my beloved friend Sooyoung."
