Maxwell wasn't normally a nervous man.
He didn't get anxious about things because he liked them to be cut and dry. Neat. Organised.
Like their proposal plan. That was the reason he liked the week plan, with a party planned at the end. They had even planned out outfits, picked out rings, everything. He liked having everything organised.
That was why all of his new behaviours as an omega were so disrupting and annoying. Making a nest didn't fit into his plans, and it was often spur of the moment. Getting overwhelmed by the pheromones of others could disrail his plans. It was why he had started his company, so that he could have control.
So, with all of this in mind, he thought he was going to be fine when Andrew approached him, surprising him with a moved up deadline for the engagement week, but he already had arrangements in place. He wasn't too worried.
