A wabi-sabi-inspired lewd expression. A restrained, non-exaggerated ahegao. If I had to define it specifically: half-closed eyes (or narrowed eyes), blush, and a mouth with the upper lip slightly raised or elongated downward, creating a languid expression. As a leading artist associated with torogao, I would name @hirokawa desu (kawayoi).
This LoRA follows the definition above while also including the conventional definition of torogao — “A facial expression where the character appears to be in an ecstatic, yet quiet and unresponsive state of pleasure.” — among the training images, with the aim of being able to express both interpretations.
