staring
睽 centers on a fixed, intense gaze: staring with eyes wide open, often with a sense of separation or opposition implied by the right component.
睽 combines 目 (eye) with 癸, which likely contributes the sound and may carry an idea of opposition or divergence, fitting the sense of staring with a fixed, perhaps confrontational gaze.
The eye 目 on the left is fixed on the complex 癸 shape on the right, like staring at something puzzling or opposing until it makes sense.
For ケイ, imagine a staring contest where you keep your eyes locked on a cake: cake -> ケイ, and your stare never wavers.
