Yup, enough anger/worry will make your body sick like that. Worst feeling ever.

Why is the chapter so short? (Ends right after Angry Arc insults snooty Noble a second time) Is it not finished yet?

Hope the author is enjoying a well deserved break~ For anyone feeling the withdrawal from a lack of new chapters, now is a good time to reflect and improve yourself or your space. Chug a glass of water! Put away that thing that’s been sitting there forever (or find it a new home)! Etc. We may not evolve like our demon protagonist, but with small daily effort we can level up in our own lives~
