They weren't THAT sure about what happened, they just know that Sophia was out for groceries, and they made chaos, that needed to be cleaned up. But they'll procrastinate until they hear Sophia's car pull up on the driveway of the KATSEYE house.
Dani and Manon were in the middle of a dodgeball match, using the furniture and a rubber ball that was just found. Not to mention, they almost broke five windows in the meantime.
Lara and Megan were playing table tennis with a soccer ball and using damn plank of the bed as the "rackets".
Yoonchae was trying to stay out of it, eating the leftover chicken nuggets shaped as dinosaurs they bought. For Yoonchae, who is the maknae. They didn't know why, they just see them as a ten year old.
Then they heard Sophia's car pull up.
"FUCK WHERE DO WE PUT THIS-" Megan shouted frantically, pointing at the bed planks in Lara's and her hands.
"WHERE DID YOU FIND THEM?!??" Daniela yelled back, throwing the ball into a basket that was always forgotten that was in their living room.
"I TOOK THEM OUT YOONCHAE'S BED!!!" Lara replied for Megan, who was running upstairs in Yoonchae's shared room with Sophia to try and put the bed planks back, in time.
