At first, I considered him as a college roommate. It's a fine idea, except for one problem. I want him to be MUCH MUCH more than a roommate.
Then I thought of him being my college boyfriend. But I have a hard time seeing him as the long-term relationship type.
How about the Big Man on Campus? Possibly, but Tyler Lough just fitted better.
So in the end, I couldn't come up with a title for him.
