You are fixing the car with Matt

"It should...work!", your brother smiles triumphantly, rising his chin from the noisy engine of your car. "Ok, I'll try once more then…", you say, doubtfully. A loud thud comes from somewhere inside the machine when you turn the key. Yet, after a moment of hesitation, the car gets running again, prompting a whooping of joy from the two of you. Swept away by the moment, you pay little attention to the buzzing of your phone. "Ok, it should be working…but now the wheels...", Matt mutters, while you skim over the message on the screen. It's Grace. "What the fu…", you shout out, angry, watching the mobile in desbelief. "I can't believe it...Grace! She is...dropping me like nothing". "You mean that she's breaking off? Out of the blue? With a message?", your brother asks, even more flabbergasted than you. The relationship with Grace was wonderful and everybody was part of it. "Yeah...she gives no reason, just said that she wants a break. Never call me again...this is not really her…". "Where is she now?", Matt demands, shaking her head, "Maybe something happened. Something bad…". "I don't know…", you reply, confused, "She had a kind of karate demonstration today...a show that her sensei put on to recruit some new girls…". "Do you know the place?", the guy asks, turning serious. "Well...yes…", "Ok! I'll take you there then". The military tone of your brother kicked in, and you know that in those situations changing his mind is impossible. Sad and upset, you follow him.
