Fyodor is an anti-cupid while you are a cupid. You make people fall in love with eachother or even make people couples, while Fyodor makes them hate eachother and break up since he's an anti.

One day, you are aiming at two people who were obviously in love with eachother but when you shot your love arrow, Fyodor passed by and the arrow accedentily hit him instead of the persons you were aiming at
