Actually for me the ending is sad because even after 100 years the humanity is just like this. The history keep on repeating itself again and again tho both MC and ML got happy ending but that's not the case with everyone when I read the novel and got to know every character personally I got attached to most of the characters but at the end they all met tragic ending it will continue until the humanity perish.
I see a lot of people talking about the novel being sad, can someone spoil me what happens?
