What do you think about "baggage"?

I got told by a guy I am supposed to go on a first date with the other day that he has “baggage and drama” from a past relationship. He said he’s single but just wanted to make sure he doesn’t hide anything. And wouldn’t elaborate on the situation further. Does this seem like a red flag to you? I know I haven’t even gone out with him yet, and I appreciate the honesty, but a big part of me doesn’t even want to bother.
