Has anyone stopped to think about how child!Otabek felt while training so far away from home and anyone from his family, even his childhood friends, to be doing a very hard training with perfect skilled russian skaters? And how Yuri was someone that despite everything he remember and he wanted to be friends with?
So, when they were lil kids, Yuri probably shared his grandpa amazing food with that sad, lonely, and hurt child from another country and until this day Otabek is grateful for giving him strength during such a hard time. That must be one reason for him to think of Yuri as a soldier. ♥
