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:
The vocals will be used in a commercial release. I need a song written from scratch - lyrics, music, and vocal melody. 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?. Check out what I uploaded. I'm an independent artist not affiliated with a record label.
