What is your biggest regret after graduation?

My biggest regret is that I didn't leave my first love's phone number.

I went to Shenzhen after graduation. At that time, my feelings for my first love were as good as ever, and I missed him very much, but I didn't have any contact with him, so I could only hide in the quilt and dream.

My biggest regret is that I didn't leave his phone number. If I had his phone number, I wouldn't feel so lonely and unloved in those years. Even if I miss someone, I can't say it.

If I had his mobile phone number, I would definitely send him a text message every day to see if he is ok. I will accompany him when he is sad and lost, and tell him that I always have him in my heart.

If I have his phone number, as long as he says "come back", I will definitely come back, because I know that if I don't come back, I will regret it.

What I regret most now is that I didn't leave his phone number, otherwise I wouldn't miss him so much.
