FBI Washington Headquarters, a villa in a community on the northwest side.
At eight in the evening, Luo An and Mona returned to the villa, and Caroline, wearing long sleeves and pants, yawned as she walked downstairs:
"Good evening, both of you."
"Um."
Mona casually replied, put on the slippers Luo An handed her, and went into the kitchen to prepare food.
Luo An nodded to Caroline, intending to go upstairs to change clothes, but suddenly noticed a large object in the room around the corner:
"Caroline, what is that thing you bought?"
Caroline poured herself a glass of juice, took a sip, and replied with a smile:
"It's a grand piano I just bought. It was delivered this afternoon by the workers."
"..."
Luo An's eyelids twitched, too lazy to talk, and returned to his room to change clothes. Meanwhile, in the kitchen, Mona with a "bang" inserted the knife into the chopping board and glared at Caroline:
"Hey, we agreed before that the room would be reserved as a gym!"
