This is as far as I can do.

I leave the house and go to the restaurant since Sando might have been waiting for me. I message Arata and Kureha and ask them if they will be working tonight, Arata message me first and tell me that he will be working but not Kureha since she has an assignment to finish tonight. I put my phone in my pocket but then it vibrates again and so I check who's messaging me, turns out it's Arata again and he says that he asked his father about the accident and his father told him what he saw. Arata will tell me everything once he's arrived at the restaurant so I can't wait to hear his father's story.
