How far back. Because if it's from when they were younger Gitae bullied Dohu.
Commenting here because I had the same question. I like the story but so much time has passed that I almost forgot the whole beginning smh
Gitae was his biggest bully at school. He was the one encouraging his classmates to call him names, poured milk on him, water on his notebooks/school supplies, etc.
When they were still in university, Gitae found Dohu once and invited him for BBQ with the excuse of apologising, but when Dohu left and was going back to the restaurant because he forgot something, he heard Gitae talking to someone on the phone, saying Dohu didn't change at all, that he was still an non-sentient robot, a psychopath, and other stuff along those lines (it's been a while since I read those chapters but I'm pretty sure of all this).
Somebody please remind me what happened between dohu and gitae?
