Can you spoil me

zaika becomes zhenyas biggest weakness

Anastasia the weapon kinda determines Zhenya’s worth at the beginning. That’s why everyone tolerates him, scared of him, obeys him etc.. He explains it as an elusive, legendary existence, his biggest strength, his biggest weakness and the reason he breathes. Later in the story Taekjoo metaphorically becomes all those things for him and he names him his new Anastasia.

He also gives the weapon Anastasia to Taekjoo once they become lovers
