Can somebody please help me find this story? I forgot the title but I remember this one scene
The boy didn't want to see people leaving or the back of the people so when he says goodbye he always leaves first without looking back but then he started letting this guy leave first to practice on the feeling of people turning their back on him as they leave then his friend told the other guy the reason why the boy always leaves first and never looks back
Please somebody help me what story is this?
