ashamed
僯 centers on the feeling of shame or embarrassment, specifically the state of being ashamed.
僯 combines 亻 (person) with 粦, which likely contributes the sound. The exact historical development is uncertain, but the character is associated with the idea of shame or embarrassment.
A person 亻 standing beside 粦, which looks like a mix of evening 夕 and rice 米, might feel ashamed if they are caught stealing rice at dusk.
For リン, imagine a person feeling so ashamed they turn as red as a rin (a made-up name for a red fruit): rin -> リン, and the person's face flushes with embarrassment.
