to long for, to gaze at
睎 centers on looking intently with deep emotion: gazing at something or someone, often with longing or yearning.
睎 combines 目 (eye) with 希, which likely contributes the sound and may relate to the idea of looking toward something rare or desired. The exact historical development is uncertain.
The eye 目 on the left and 希 (which can suggest rarity or hope) on the right: imagine an eye gazing hopefully at something rare or longed for.
For キ, picture a key you long to find, gazing at every lock: key -> キ, and your eyes search with longing.
