hunger
醺 centers on hunger, a state of craving or emptiness.
The exact historical development of 醺 is uncertain. It visually combines 酉 (sake jar) and 熏 (smoke, scent), but how this relates to hunger is unclear.
Imagine a sake jar (酉) filled with smoky, aromatic liquid (熏) that only makes you hungrier instead of satisfying you.
For クン, picture a hungry raccoon (クン) sniffing around the sake jar, hoping for food.
