call out to and deceive
唀 centers on using speech to lure someone into a false sense of security: calling out to and deceiving them.
唀 combines 口 (mouth) with 秀, which likely contributes the sound and may relate to leading or drawing out, fitting the idea of calling out to deceive.
A mouth 口 beside 秀, which looks like a person with a prominent head and flowing hair, suggesting someone using smooth talk to lead another astray.
For ユウ, imagine a deceptive call of 'you' luring someone closer: you -> ユウ, and the mouth 口 draws them in with false promises.
