Search Results: get a guy to fall out of love with you

So my story is basically a shounen anime type story. Humans are given special powers by spiritual aliens named Kuducho, and then become Hinajins, which are basically superhumans, who can't be damaged my manmade weapons. The price for these powers is half their life, which is then added onto the Kuducho's life.

That's the main idea, but my main focus right now is developing how I want the characters to be like. I'll develop the overarching plot, and fix possible plot holes later on. So without further ado...

Recon: Main character of this story. Pale skin, medium length brown hair, 5'11, 18 years old. He's a pretty socially awkward guy, and isn't really popular anywhere he goes, but he really cares for everyone around him, even if they don't give a shit about him. He believes there is good in everyone, and believes everyone can be reasoned with. He has green electric powers, since its his favorite color. His powers are more on the defensive side, creating a spiky shield of electricity around himself and the such.

Luna: The deuteragonist of this story. Light brown skin, dark brown hair that's butt length, 5'7, 19 years old. She's Recon's girlfriend, and they fall in love pretty quickly, as I want this to be a more action focused story, and not a "getting the girl" type of story. Recon doesn't need to "get" her because they're already together, and already love each other. Unlike Recon, she's very extroverted, cheerful, and optimistic. She's very friendly and tries to be friends with everyone. However, she realizes when people can't be reasoned with, or are just bad people. So she's smarter than Recon that way. Her powers are more about speed, hitting her opponent before they can see her. She has water powers, and can summon powerful water based attacks with the humidity in the air.

Willow: Tritagonist. Has the power to summon blue flames, and control air. He's very aggressive, and Recon's biggest rival. He's very brutal towards his enemies. He's about attack.

I know there are so many questions on that topic and I don't want to annoy y'all with bringing up that stuff again.. Also, I'm not the misogynistic type who blames women of being shallow or anything, so please be brutally honest! I love women and I have lots of female friends who I really like and care about!

I just wanted to know what your opinions on my situation are.
Since my start at university, I'm into a girl from campus who is taller than me.

I'm 5'7
She's like 5'10

When I walk past her, she sometimes looks at me like she was annoyed by my presence or something. Or maybe that's just paranoia? As far as I know, she's single, but she's always hanging out with all these hot girls and the cool tall guys so I've never felt comfortable talking to her so far. Once I heard her talk to a friend about a party they'd been on the night before, and when her friend told her that in the end she went home with "that hot guy", my crush went all euphoric and said something like:
"He was so tall!"
Does that tell me that height is super important for her? Or should I keep calm and rely on the fact that there are other qualities to impress her with?
I've talked to many of my female friends and they all told me that the female preference for a taller guy is universal and very strong and that I should stick to girls my height or shorter. The chart I put in the description also says that girls are very strict with their partners height!
The problem is that it isn't just her. I've always been into tall girls like 6ft or even more. Maybe that's the reason I always get rejected and never had a girlfriend...
I feel like I don't like her despite of her height but because of her height, like I love her big long body.
Is there any hope for me? Are there girls who can actually fall for someone who is a couple of inches shorter?
Please be honest!
