(Durarara!!) Ikebukuro's Strongest

This is probably a story about a girl whose personality gets a little warped as she goes from a secret crush to openly pursuing him, and in the end, who knows whether they get their happily ever after. I wrote this Shizuo Heiwajima romance according to my own ideas. But halfway through, I read too many Shizuo x Izaya stories, and the writing got weaker and weaker... I almost couldn't stop myself from turning it tragic and pairing Shizuo with Izaya... But at least I finished it. I originally planned to stop at 5,000 words, but I couldn't help myself. If I kept going, it would turn into a full-length story TOT... As I got further into it, I found Shizuo Heiwajima harder and harder to write. I was afraid of getting his character badly wrong, so I ended it here, with the story still hanging in the balance. Because I don't think he'd fall for someone easily. The first part is snarky; the second part is possibly a girl's romantic daydream... Premise:
