perfume
馥 centers on a strong, pleasant scent: perfume or a rich fragrance.
馥 combines 香 (fragrance) with 复, which likely contributes the sound. The character expresses a strong, pervasive scent.
The left side 香 means fragrance, and the right side 复 looks like a container or repeated action. Imagine a perfume bottle being opened again and again, releasing a rich scent.
For クク, picture a cook cooking with fragrant spices: cook cook -> クク, and the kitchen fills with perfume.
fragrant; sweet-smelling
