Are muscle pain after workout really enough to nearly immobilize people? Because yes when i worked out my muscle went sore as hell after a day but can still do most of the daily stuffs that I do.
I pity the mc because he have the same constitution as Grimm, a tragic hero and have simillar lifespan as red hood. Like Grimm, they also both killed their lovers at least once. And it seems like there is also an entity that is manipulating his memory just like Grimm.
