The heroine of the story that you play as is always female in every route. Your love interest, Kuro, is always male :3
The reason that Kuro looks so feminine is because I'm not an artist, and at the time of making this, I only had access to limited sprite resources, so I had to use female sprite bodies in the generator software I'd purchased to try and make them look as male as possible, haha. So while Kuro's appearance is pretty feminine, he's male.
