守恩 is a virtue-based given name common to both Han Chinese and Korean speakers — Korean 수은 (Sueun) shares the same characters. Literally "to keep / hold on to gratitude" — naming a child this expresses the parents' wish that they remember kindness received and grow up grateful.

守 (to guard, keep) + 恩 (kindness, grace). Compare with the related virtue names 知恩 (zhī'ēn, "know gratitude") and 报恩 (bào'ēn, "repay kindness").
