@LaraWesterholt this has nothing to do with yuri or the bullies or with dong ...this all happened because of trauma and the feeling of having nothing with you even if you do ...its a life where it's filled with darkness and yuri was bright and how much he wanted to be him he knew he couldn't because of hatred towards himself ...so yuri being kind ,bright and dependent with the situation he blames yuri ...if u imagine it ..at one point we would too ..it's a sense of jealousy and admiration altogether
