Miharu Yuki, from Gozenchu's manga Kore wa Ecchi Counter Desu ka? (これはエッチカウンター ですか?) Trained on a number of images from the manga, it includes some NSFW so be aware. I've assumed black hair and brown eyes for the samples. Reuploading as Civitai seemed to have a brainfart with the first.
Prompt:
MiharuYuki,black hair,brown eyes,glasses,large breasts
