ugly
儖 centers on physical unattractiveness: being ugly or unsightly in appearance.
儖 combines the person radical 亻 with 監, which likely contributes the sound. The exact historical development of the meaning 'ugly' is uncertain.
A person 亻 standing beside 監, which suggests watching or inspecting. Imagine someone being scrutinized so closely that every flaw is noticed, making them appear ugly.
For ラン, picture an ugly person running away from the inspection: run -> ラン, and the person 亻 flees the watchful 監.
