The sheer amount of irony in your statement leaves me speechless. Any retort I make to try to make fun of you cannot possibly be any more damaging than what you just said (which I will now screencap).
I'll try: What you have barely qualifies as a concept over a 'fetish.' And not even a proper fetish by the sounds of it; a 'fetish-of-the-week' kind of ilk.
That kind of 'concept building' (I use quotes here because I'm being generous here and I don't want you to actually think that what you just did was actually build a concept) is flawed on the get go. It's like saying "I want to write a story where a white guy hooks up with a black lady. I don't see that too often," and then go from there. It's more pornography than the basis of a story.
Maybe you should take more time about the setting around them, the situation that they're in, or the kind of people that they currently are and want to be? Just a question that you can get from any Writing 101 self-help book.>>93612720
Also OP, it's "albeit," ya dumb fuck.
My advice? Well, firstly, what you have now sounds flat, uninspired, and generic. But whatever. It sounds like you're starting out, so first thing's first: Write this story knowing that it's going to suck. And then just experiment with whatever the hell.
You don't have any other characters, you don't know what it's about... but you certainly like your protagonist (for some reason...), so, just start there. Draw a one-strip or one-page comic of this guy doing something and how he reacts to it. See how he grows. You'll eventually find problems for him to solve and characters you want to interact with. J
tl;dr just fucking start without thinking. Thinking clearly isn't your strong suit, so just figure out how to have fun.
