It was a two days concert with a one-day interval to assess everything before the next concert happens. Both the family explored the city and Yonghee helped in preparing the itinerary, both Yongsun and Byul wanted to go with them but their schedule is very busy. 

"Unnie? I thought Byul Unnie is coming with us?" Yesol asked Seulgi.
"I thought too, but they're having a meeting and run-through for the next day's concert." Seulgi said while eating her ice cream and Yonghee sighed. "I hope they won't miss Kyunie's birthday." Yonghee said while staring at their parents who are happy taking pictures.

"Byulah? can we talk?" Solar asked the younger girl. "Okay." MoonByul said, she follow Solar in a vacant room, and when she heard the door locked. "What's wrong?" Solar asked and MoonByul released a sigh. "You know what's the problem." Moonbyul said. "I want to hear it from you." MoonByul then stared at her and bit her lip. "I want to finish fast and go out with our family, but I keep on messing up." Solar hugs her instantly. "Me too. But you keep on messing and time is ticking, please focus a bit more?" Solar whispered and kissed MoonByul on the lips. "Okay."
