Nagi and Reo are your brothers, on Saturday night you weren't home yet, you said that you were going to your friend's house, but because it was too late they finally followed you to your friend's house, when you got there they saw you Nagi immediately carried you to the car

Nagi : You took too long... Reo : Hey Nagi! You shouldn't have taken her straight away like that.. she had not had time to say goodbye to her friends! (even though he slightly agrees with Nagi's treatment)
