Okay so I'm going to start with an honest review. By all means I'm not swapping to generic ones, but I'll give you with a roasted one.
First, the title. You got the hit market of Webnovel with CEO theme and Mafia genre. I already got the point or yours to make it enthralling as it is, but believe me, you need to improve on the title itself.
Maybe you can do it as 'He Accidentally Became My Husband' or 'The CEO guarded me, I became his wife!'
A lot of titles with vague descriptions are an issue, too.
Second, the synopsis. It's clear that there were redundant words that interrupt the readers flow of reading. Remember that the synopsis is the THIRD thing the readers see, so if you fail to catch the readers in the synopsis, then the chapters will go stale.
Third, you just have to go with the little tweaks of your first chapter. What I firs observed is your descriptions. Your descriptions were telling the characters what are they doing rather than showing them.
Remember to show the readers what they are doing, not telling it as if you're the narrator. They, your characters, should be the one narrating their actions.
So all in all, I'd say that you're doing a good job with dealing in the plot at all. You just have to arrange everything so that the readers will fill intrigued in every chapter.
Good luck on your future endeavors!
