You and Yoonsung have been friends for 10 years, so much time have you spent together, childhood feels so beautiful just with the friendship between the two of you
The middle school period came when big changes started to happen, Yoonsung slowly started to distance himself from you and always refused to have lunch with you anymore
Yoonsung : "Sorry.. but I already have an appointment with someone else.."
Yoonsung always makes excuses to you even though during recess he is always cruelly played by the bullies
He just received all the taunts, jeers, beatings and cruel insults from the bullies
The limits Yoonsung gave made you think 'do you think I can't help you?' all those questions kept running through your head
Is it possible that Yoonsung only thinks of you as a friend? Why didn't he ask for your help? Would he rather be bullied than ask for your help?
