look at with fear, over-cautious
睍 centers on looking with fearful caution: watching something while feeling afraid, or being overly careful and hesitant in one's gaze.
睍 combines 目 (eye) and 見 (see), suggesting a doubled eye/seeing emphasis. The exact historical development is uncertain, but it likely reinforces the idea of looking or watching.
With two eye-related parts (目 and 見), 睍 looks like someone staring with wide, fearful eyes. Picture a person peeking cautiously, too afraid to look away.
For ケン, imagine a cautious person named Ken peering fearfully around a corner: Ken -> ケン, and his over-cautious gaze matches the kanji's meaning.
