What is sad about falling in love, talking about short sentences, being sad, falling in love and talking about short sentences?

1, that's all the warmth in my life. I gave it to you, but you left me. How can I smile at others in the future?

2. It's probably inappropriate that I can't make you laugh, but you will only make me cry. Then I said I was leaving, you didn't stay, and I didn't look back.

You are drunk and your eyes are full of tears. You said you were so tired that your lover would never come back. Who will you love in the future?

I don't know when it started. Finding you in the crowd at a glance has become the best thing for me. Where I miss you, I can see you.
