How Much Do You Know About the Past?

Who has never loved someone desperately, spent all their thoughts and courage, couldn't control themselves, and ended up not being together. He is your youth. We always fall in love with that person at the wrong time, in the wrong place, and then have to spend our whole lives forgetting them. The past is still so clear, but it is out of reach. All the beautiful past that belongs to us cannot be returned. Maybe we are just one step away from happiness, and it was this one step that made me lose so completely. I have walked such a long way alone, please don't call me, I'm afraid I still can't help but look back, I'm afraid that no matter how determined and unyielding I am, I will still turn around and run to you when I hear your voice, and then you throw me away, leaving me to fend for myself.
