When I was 18 years old, I opened the door to a new world because of his birthday and walked into his youth. He was a god-like existence in my world, and I played an unfamiliar role in his world, but I was unprepared to break into his originally peaceful and trouble-free life. I came on his birthday and left on an unknown day. When I found out that he was just a passer-by in his life, I chose to let him go. Because I really hope that one day I will appear in front of him arrogantly and say to him: I understand you, I like you.
