Tongue
The tongue radical and the tongue kanji are exactly the same! Yee-haw!
ぜつ
した
None
You’re sound asleep in bed when your tongue drops out of your mouth and you start to drool, getting saliva all over the bed sheet (した). You wake up with a soggy patch of sheet near your mouth and wipe the drool off your face. Your significant other sees the whole thing.
Your significant other had been watching you sleep with your tongue out for a while now, so you're super embarrassed you wet the sheets with your nasty tongue drool. You feel very judged and embarrassed.
