Writing Quality is 4.3/5 from me since the way the author describes things were easy to understand and wouldn't be much problem unless you're such a picky grammar reader.
The update's stability is five, considering how the author able to update many chapters on the same day.
Looking at the way the story goes fairly smoothly and logically without any hint of awkward development, I guess 4.7 is not a bad rate for the story development.
Here's the unique. The MC was a gambler, but unlike any other gambler, he is surprisingly the opposite of a bad gambler, a good gambler with family being the centre of his life. He was bold enough to leave his job/hobby as a gambler to make his family's relationship goes well.
The MC's wife also quite mischievous and tend to prank MC and her son. There is this moment where the MC's wife also broke out in tears upon knowing the MC's source of money was entirely came from gambling. This shows how MC's wife is another human being and not an expressionless robot, unlike in some novels.
The MC's son was designed like a child of his age. Full of curiosity, childish, and reckless.
The author has described the world background perfectly at the start of the novel. Hence, 5 stars from me <3
