"I told you clearly to come back at eleven, look at the time, and look what time it is, IT'S ONE IN THE MORNING." A trip to a party is the reason Hitoya was now so angry, so much so, that he himself went to pick you up. He threw the helmet at you, waiting for you to put it on while he was figuring out the motorcycle's engine...by the way he sounded and acted, you had really tried his patience.
