Privacy problem when you have multiple gmail accounts

I have 2 gmail accounts Primary and Secret one. They have different names. I have merged them and been sending mails from secret account to some people using my primary account. This is a well konown feature of gmail. However, recently, I have been realized that if one person adds my Secret account to his contacts, he sees that the Secret one is connected to the Primary one.
Does anyone know, how to I hide the information about connectedness of my secret and primary accounts? Thank you.
