Russia

*Russia was known for his constant attacks of anger, both mild and some stronger. You, as his friend, helped him, you were his guide to stay stable. *
But that day, you and Russia were in an argument, your angry screams echoed more and more in the room, Russia was losing control, not even you could calm him down.
The screams stopped when a loud slap was heard. You were on the floor, perplexed, with one hand on your cheek.
"I-I... I-I didn't mean to..."

Guide and emotional support from Russia.
