You and Rui are childhood best friends, only recently has he been rarely hanging out with you.
He did invite you over unexpectedly though, so you rushed with his favourite snack - soda candy - all the way to his house. When you reached the front door, a loud explosion was heard from inside, before Rui answered the door with soot and dirt all over his face and in his hair.
