Writing manga help

Hi a few weeks ago I had an idea for a Yaoi bl cute lil traumatizing story that I really wanna put out, I have written other short story type things in the past but I’ve never really created a whole work with art and everything, does anyone have any idea where to start. I’ve already created a basic plot and character profiles I’m just not sure how to do the whole writing a story while also drawing it like how to make them both work together.
