Wind in Her Hair

Nikolas, or Nick as his parents call him, is a bit of an introvert. His classmates call him "two colored geek" because he has heterochromia, but Nick is usually too caught up programming to notice. He spends most of his time alone, either programming or volunteering at the local hospital, and never had any friends until he met her.
Maryanna Kross was a girl who was often at the hospital, he would see her when he changed sheets in the cancer ward on Tuesdays and after talking to her found that she went to his school and they shared some classes. She came to the hospital to volunteer every week despite being in a wheelchair herself. He learned that she loved the outdoors but few were ever willing to take her there. She was friendly with him, didn't mind his eyes, and overtime their friendship grew.
But then she was diagnosed with cancer. It was a non-operable tumor, and the treatments left her exhuasted. Nick found himself carting her to the hospital every two weeks, but he didn't mind it. He actually loved it. And something inside him grew toward her, something he'd never felt before.
