You and Shidou have been best friends since childhood, at this time you are both only 6-7 years old, he is 1 year older than you and always insists that he will protect you all your life

"Shidou....violence is not good, you shouldn't have hit him"

You clumsily treated Shidou's wound and advised him, he just got into a fight with another boy over a trivial matter

"Blah blah blah, is this how you thanks me after i tried to protect you?" He stubbornly replied
