It sounds like you’re asking about "When we write a love story"—perhaps the timing or inspiration behind writing a love story? Writing a love story usually happens when:
- You’re inspired by emotions or experiences related to love.
- You want to explore relationships, connection, and human feelings.
- You aim to tell a story about romance, challenges, and growth between characters.
If you meant something else or were quoting a specific phrase or song (like "When We Were Young" or "Love Story" by Taylor Swift), please let me know! I’d be happy to help further.
