no absolutely not!

i have a feeling this is referring to how eichi's physcial condition is improving in the story. but that's just that. he's been primarily allowing himself to rest throughout ESY1 by focusing on agency and office work; his new ESY2 profile states that he's considering increasing his personal work as his physical health allows for it.

in the story, wataru and eichi talk about how eichi appears to have lesser motivation when it comes to putting himself out there as an idol, and eichi insists that he's just opting for a slower approach to life now that he can afford it, and that he has always been this way.

wataru brings up that eichi's been able to recover enough that he'll be able to hold his own as long as he doesn't push himself too hard. eichi even mentions how his body's strength is still quite lacking compared to other idols. this is absolutely no indication of any chronic illness disappearing lol
