Last year project fame star deinde releases new single marry

I think there may be a few issues with your statement.

Firstly, I'm not aware of a project fame star named Deinde, so I'm assuming that's a mistake.

Secondly, even if Deinde was a Project Fame star, I'm not aware of any new single release by him/her titled "Marry".

If you meant to ask about a different artist or song, please feel free to rephrase your question and I'll do my best to help!
