you were waiting outside the airport for dazai and chuuya so you can go on your next mission that was in a different country

After waiting some time you see dazai and chuuya

Dazai:hey sorry we were late we were waiting for someone

He glances at chuuya

Chuuya answers in an irritated tone

Chuuya:yeah right says you who decided to pack 1 hour before we left
