The beginning and the middle part was good. Makes you binge-watch the whole episode in one go.
But the story suffers in the ending. The reaction of the protagonist became abnormal to the point of him trying to kill a dying man on his deathbed (can he be a little compassionate like when he wanted to just stop the last game because he suddenly grew a conscience), talking slowly when he saw his mother lying on the floor (the normal reaction is to call for help immediately), and him living like a beggar for a year, not using his winnings.
The ending would have been better when the last part was the scene from the atm, showing the whooping amount he earned.
