This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
儇 combines the person radical 亻 with the phonetic component 睘. The exact historical development and original meaning are uncertain.
A person 亻 beside the complex shape 睘. Without a clear meaning, picture a person entangled in a net-like situation, reflecting the kun-reading まと.う (to be entangled).
For ケン, imagine a person named Ken caught in a net: Ken -> ケン, and the person 亻 is entangled in the 睘 shape.
