The Hashiras would likely show concern. Some, like Shinobu, would immediately start looking into possible medical solutions. Giyuu might be more reserved in his worry but would still keep a close eye on Tanjiro. The other demon slayers would also be affected. They look up to Tanjiro, so his sickness would lower the morale of the group. They would try to support each other while waiting for Tanjiro to recover.
I'm not sure specifically what the 'glmm sad story' is without more context. It could be a sad story related to a Generalized Linear Mixed Model (GLMM) in a research or academic context perhaps. Maybe it's about some difficulties or failures in applying GLMM in a study.
Once upon a time in Gacha Life, there was a girl named Lily. She met a boy named Tom at a virtual party. They immediately felt a connection. They started going on virtual dates, like picnics by the digital lake. But then, a jealous character named Lucy tried to break them up. However, their love was strong and they overcame all the obstacles and lived happily ever after in their Gacha Life world.
Tanjiro might use his sense of smell to detect hidden threats. Since his sense of smell is super - enhanced, he could sniff out any demons or traps in the way of saving Rengoku. For example, if there are demons disguised as allies, Tanjiro would be able to tell by their scent.
One common theme is unrequited love. In GLMM, one character may love another deeply, but the feelings are not reciprocated. This can lead to a great deal of sadness and longing.
One GLMM sad love story could be about two individuals from different social classes in a fictional world. They fall in love but society's rules and expectations keep them apart. For example, one might be a noble and the other a commoner. The noble is pressured to marry within their class for political reasons, and despite their deep love, they are forced to separate, leaving both heartbroken.
