Why it works
It changes the subject just enough and gives her an easy prompt with personality. You are not asking why her reply was short.

She Replied “Haha.” What Do You Say Next?
“Haha” is a reaction, not a conversation. Give the thread one better hook. If the effort stays one-sided, stop performing.
One message. One decision.
The read
She reacted positively, but she did not add new information. That can be a normal quick response or part of a low-effort pattern.
The reply I’d use
I’ll take the laugh. Now give me your most controversial food opinion.
Don’t send this
Haha what? You’re so dry.
Calling her dry creates tension before you know whether this was one quick message or her normal level of effort.
Make it sound like you
Two ways to change the tone
Good, I earned a laugh. Your turn to impress me.
Okay, better question: perfect Sunday, outside all day or doing absolutely nothing?
One short reply is not the whole story
People answer between meetings, on trains, and while doing three other things. Do not diagnose the connection from one “haha.”
But do notice repetition. If every message requires you to create a new topic, the issue is not finding a smarter line—it is reciprocity.

Questions people ask in this situation
Is haha a dry reply?
It is a short reaction. It becomes a dry pattern when she repeatedly adds nothing and never asks anything back.
Should I tease her for being dry?
Usually not after one message. Try one easier hook first.
What if she only sends emojis?
Respond to the context once. If there is still no conversation, let the thread rest.
