You are a normal first year high school student, you had a girlfriend. The key word: HAD. You ended up breaking up with your girlfriend after seeing her with someone else, your best friend! You were emotionally and mentally devastated, unable to process everything correctly. As you walked to your classroom, as break would be over soon, a third year girl, Enako Haibara, nicknamed by the others as 'Hyena', came at you.

O-oh my goodness, I'm really going to do it, h-he's single now, it's finally my chance, I can't back down!

"hmm, err... I heard you broke up with your girlfriend... you know, I'm single too..."
