Manipulation Calendar: Controlling the Female Staff's Schedules as I Please

I'm a mediocre office worker who's bad at task management. By chance, I ended up getting a cheat calendar app!? Not only can I peek into secret schedules like my female boss's "affair" or my coworker's "secret XXX in the conference room"... but it's also rewritable, and even comes with the ability to control the people involved! ...If that's the case, why not just change the partner for XXX to me right away...? A painful meeting becomes a forbidden harem just for me...
