Question about "his cure" story

[Nekomancer]

Hi, so as some of you know I have the first chapter out of slightly fantasy sneeze fic out (it has a healer and a mage with allergies + asthma... Long story short they make a pact to help each other her to practice medicinal magic and him to get stronger and be able to use magic outside for longer) and I planned for it to be a little long... But that was ages ago when I first posted it. Overall my writing has improved and changed quite a bit over the past year so I'm considering rewriting the first chapter as I put out the second chapter? However this will take slightly longer as I have to do two at once. So basically my question is would you prefer a faster second chapter with a new writing style? Or a rework altogether? It'll be the same story either way just written a little differently. Thanks for anyone's input!
