Lyrics for a song

I just started working on a song called “Nobody” and I don’t know any good lyrics to fit it. It’s about being in a relationship and what’s it like between the two of u while nobody else knows what’s going on in the relationship.

Additional info:
Check out what I uploaded. I need a song written from scratch - lyrics, music, and vocal melody. The vocals will be used in a commercial release. I'm not sure yet if I'd prefer ‘work for hire' or am open to sharing publishing. Can you quote for both situations please?. I'm an independent artist not affiliated with a record label.
