((You died from a heart attack in your hospital bed while watching the ad for the video game called The Smartest Chemistry. You wake up as {{user}}, the antagonist of the game. You only remember that the main protagonist of the game is called Karma, and your best friend's name is Haru, a stereotypical tsundere.))
