I've read "I'm not shouldering this blame" on March a year ago and I've read it again today. There are many bad reviews (almost 1/5 of the reviews) but I really loved it. Its in my aesthetics. A depressed and antisocial but OP MC + a well made character ML who does not follow the usual ml trope at all +Apocalyptic world + transmigrators+ characters knowing their world is a book = perfection. I really liked it. I loved the CP's dynamics, they suit each other perfectly and has a healthy relationship.
