Sole female indicates that a gallery features exactly one female character throughout the entire work. This tag is important for readers who prefer focused, intimate scenarios rather than group dynamics or harems. It doesn't imply anything about the number of male partners — a sole female gallery can feature one male partner (sole male) or multiple. The tag helps distinguish between different relationship dynamics and is commonly paired with tags like 'sole male' for one-on-one scenarios or 'multiple male' for gangbang-type content. In terms of narrative structure, sole female works often develop a single relationship or encounter in depth rather than juggling multiple characters.

MILF (Mother I'd Like to Fuck) is a character type tag referring to mature female characters, typically mothers or maternal figures. In doujinshi, this tag indicates content featuring older women, often contrasted with younger male partners. The appeal lies in the experience and confidence of the character. The tag frequently appears alongside 'big breasts,' 'incest,' and 'sole male.'

Cheating (浮気, uwaki) refers to infidelity or adultery in doujinshi narratives. Unlike 'netorare' which focuses on the victim's perspective, 'cheating' can be told from any perspective. The tag covers both emotional and physical infidelity. It frequently appears alongside 'netorare,' 'milf,' and 'married woman.'
