Sorry, this image was generated using not only prompt, but also "img2img". First I uploaded an image such as "1 girl image" generated by myself or favoirite images found in Danbooru. Secondary I modified it using 'Edit Image'. For example, I added a shadow looking like a man's silhouette. And then I generated images with Strength 5~7, repeated several times to complete it. As you said, "1boy" frequently disappears... but if you use 'Edit Image', he might show up.
Adding onto @x_u's comment, if you're using novelai, then try using 1 boy and use the curly brackets "{ }" on it. They add more strength to whatever tag(s), sentences, or descriptors they're used on. It's especially good for things that have trouble generating so you can "force" it to hopefully get the desired result.
