just a random analysis I thought
when Mike responds to Will "We're friends" it remains very strange. He could have said the same sentence in different ways, he could have said calmly and like a normal person, but he went straight to a more aggressive and defensive way.
If he were a straight guy he would respond calmly, but the "What about us?" hit him hard. It was Mike who understood it as romantic (and Will didn't even mean to when he asked), and Mike already panicked for a "straight man".
The way he and Will were arguing, anyone watching from afar might think they were a couple fighting, and if that's what Mike would be afraid they would think? Did him get defensive so quickly so that no one would think they were dating.
