spoil me down the drain i need to know if kim dokja's actually a hygine freak [spoilers]

I saw some people talk about how kim dokja and yoo younghyuk are both hygine freaks which shocked me beyond belief never in 400 chapters has that man mentioned even thinking about brushing his teeth and i'm supposed to believe he's a hygine freak??

I always thought he immedietly forgot about it because even before the scenarios he was depressed and upholding his appearance or maintaining any routine he had in life was always a concious decision he'd make every day and him realising he's not even trying to look clean why the rest of the members are washing their hair and all was him noticing the actual contrast between him and others

They mentioned the moisturiser skill but most of the time skin care has little to do with actual hygine it's more of a beyond strictly for the pursuit and maintanance of beuty of the skin and i think the fact that they only mention that skill is a proof to what i said because they never talk about a deodorant of floss skill but they would if he actually cared about hygine right?

Plus yoo younghyuk says kim dokja wants to be an idol when he Heard about the moisturiser skill making me feel like he doesn't usually buy the only skill connected to hygine i've seen so far making me believe they're both stinky fuckers and certainly not hygine freaks no action they've taken so far made me feel like either of them cried to their dentist to look thrice because they felt a tingle or stop in their tracks to get all the builtup from underneath their nails and cut them

Please tell me if i'm wrong and if kim dokja actually never mentioned brushing his teeth because he planned using the bacteria in his mouth to unleash a dragon breath of plague or something

Or if there are hygine centered skills i'd hear about later on even if it was somehow a huge spoiler because like i'm curious about that

Because the idea is so alien to me i literally feel like if they shook hands and one went to wash his immedietly after the other would feel betrayed but i might be sleeping on thousands of years worth of showering related lore
