What started off somewhat promising quickly deteriorated into mediocrity and then the characters just became annoying which left little remaining to enjoy. There are definitely a few positives to take from this series and despite what I've said it is by no stretch awful or unbearable. If you want a short series for a yearly MAL challenge or have decided to invest in Stocks following the fall of the market due to Corona then you might get something small out of this series. Even then you're unlikely to find anything much in this extremely brief look at stocks and the life of a rich girl who doesn't know anything of the world outside her job.
The single biggest problem with Billionaire Girl would have to be the fact that while several plot lines and issues revealed themselves none of them were actually dealt with. This manga is a whole bunch of nothing happening for 17 chapters. You'll find hundreds of other romance series where a thick headed main character struggles to realise they're in love so you may as well skip this one.
As a side note, if you're surprised by the high scores others gave this series make sure to check when their reviews were written, you'll notice all the high scores came 9 years ago when this manga first started publishing and long before it finished.
