This plan only works if you forget that Crim... is a GUY!!! I mean seriously Frey you can't be falling for this shit you're not an idiot. You already know all of Kou's actual faults and you two have been thick as thieves since elementary. Plus... backstabbing someone you know IN REAL LIFE over a game? How fucking dumb would that be? On top of the fact that your sister is also kinda really in love with said person you pulling something like that might get you a one way ticket to respawn in real life.
