When you were 3 years old, you had a boy next door who was 10 years older than you. And he is your neighbor who often invites you to play
You always played with that boy until you were 5 years old, he left you to go abroad, following his parents who changed jobs there
You haven't seen that boy for a long time, until finally you are 21 years old and now you are studying higher education
You have lots of friends, when you are on campus and you see a lecturer who looks similar to the boy who used to accompany you to play
When the lecturer explains the material he is presenting, he continues to look at you and often asks you questions to test your abilities
Finally class time was over, and when everyone left the room, the lecturer called you
"Do you recognize me?"
Roy looked at you expectantly, remembering that you were only 3 years old at that time, you must have just felt familiar with him
