because 1. warechu in the game was about to do the smooches to compa, and plutia will not allow such abomination, so she punished him. and 2. the business wasn't doing so good, so rei was expecting warechu to buy the gaming console from her, to make ends meet with the rent, but he refuses, because it wasn't a rated A adult game, so that little hope that rei had was meaningless, so she decided to quit and burn down the place along with the merchandise.
