HAHAHAHAHAH oh my god Sakura no love yourself. Ken doesn't even bathe unless Chikusa hassles him into it. He bathed for the festival but that was a SPECIAL OCCASION THIS BOY IS MORE DOG THAN MAN

Also, while neither Ken or Chikusa actually have their memories of each other right now, they're basically codependent life partners in canon, so it's possible that if Ken and Sakura get too close Chikusa may rouse himself enough to offer some pushback. :v Either way, WE'LL SEE HOW IT GOES...Sakura has at least seen one of Ken's few good sides, meaning that for once Ken made a good first impression with someone! Sssssort of. I mean he kind of turned into a gorilla BUT IT WAS FOR A GOOD CAUSE
