@Rui_Vs_ i think he went insane and i think he developed multiple personality disorder cause of it, probably because of his work as a writer getting overshadowed by newbie he started losing himself and his worth and that even though the was the case he was getting rewarded for it with a loving family, popularity and income.
he/him i like reading manga, manhwas and visual novels!, i seem to have a soft spot for fantasy media
