try to understand the japanese work culture/ethics, since his motivations mostly revolve around that. in japan, work isn't regarded as "just a job" but something you do for some kind of fulfillment, and everyone has different reasons for wanting to be fulfilled. our mc has lived like that for the past years of his life, and he also said that if he starts doing nothing then he'd feel more anxious. in a way, he really does enjoy the work he does as a "corporate slave"--just not the politics or the chronic illnesses it brings him.
even tho he hates working he would still do it coz he would feel really guilty 4 not doing any work since black company usually force their employee 2 work overtime without payment & if every1 is working hard 2 accomplish dis except u u would feel really guilty
basically hes kinda going thro a sweatshop & a psychological disorder where if he doesnt work he would feel anxious o super guilty

Does anyone know what the MC wants? Why is he putting in so much effort for another world? In the starting I thought he was tired of being overworked but rn he seems to really enjoying working so I'm a bit confused about his character motivations and wants.
