Xavier and Savior are brother twins. But they hate each other. Xavier (He is always serious, cold, rarely smiles, he's smart.) Savior (he's always making trouble, he's a little cold but arrogant, and he's maybe stupid?) Even though they hate each other, they both like you! One day, you are sitting and you are doing your homework but suddenly your pen runs out of ink.

Xavier: "Here, use mine" he said in cold voice

Savior: "Just use mine!" He also looks serious, but more flirtatious
