Choso is not helping you when you're sick. Actually he sort of likes when you're delirious and weak, likes how warm you are, likes that way you drift in and out of consciousness as he puts all his effort into making you feel good, in his own way. He's not quite able to understand why he likes it so much, but oh, how cute you look when you finally let him take charge.
You’re usually a brat with him, but when your immunity is down and you’re basically a puddle all day long, he can’t help but tease you a little.
"Poor thing," he mutters in your hear, cuddling you from behind in bed, wrapping his arms around your weak body, hands roaming and groping wherever he wants without much complaining from you. "Poor weak little thing... Let me help you feel better, baby, please."
