I know that Vocaloids don't have a canon personality but this is how I am depicting them. I hope you enjoy.
Entering the hospital room quietly and carefully,the usually energetic and cheerful blonde girl stared at the sleeping boy on the bed. He had a similar shade of blonde in his hair, his face was serene as his chest rose up and down every time he took a breath, a reminder along with the beeping of a machine that he had made it through the surgery safe and unscathed... Partially. His eyes... She remembered how they would sparkle when she made him laugh or when he got an idea that would make others look at them as if they were crazy. She smiled sadly as she recalled those memories that would be forever lost in the past. How they would go to the beach and collect seashells until the sun went down. How they would feed the birds at the park until they were too full to were crazy. And that's why they loved being with each other. Tearfully, Rin sat down next to Oliver's sleeping body. She couldn't bear to see the newly wrapped bandages that covered the now empty eye socket where his red eye should be. She loved his mismatched eyes, no matter what people would say about them. His now single eye was missing its partner. All because of a stupid cancer that infected his eye. Fortuantely, one eye could be saved, preventing Oliver from being completely blind. Just then, Rin started to lie down next to him on the bed, Rin jnew that it wasn't a wise choice and she was scared that she might injure him accidently but her body had a mind of their own. It wont't listen to what her brain was trying to do. After settling down beside him, Rin started to feel more and more worried. Fearing that Oliver might not wake up to meet her, she started to feel another set of tears rolling down her face. Her heart felt like it was tightening in her ribcage as every second passed without him waking up. The doctor warned her that she must be prepared for the worst as Oliver was hard to deal with on the operating table and that the other eye may have to go if his condition worsens when she pleaded him to let her visit Oliver. She gently touched his cheek and felt that they were surprisingly warm. Feeling somewhat comforted, she grasped his hand which felt warm too. Suddenly, she felt someone staring at her. Looking up, she saw Oliver's Yellow eye looking at her with that sparkle that she missed. The boy gave her a small smile that let her know that he was indeed alright! She felt his hands squeezing her hand with his that she was grasping before. Looking back into his eyes, Rin's eyes flowed with even more tears but this time, it was tears of joy.
If it won't trouble you too much, you can always leave a review to tell me how I should improve on my writing. Good Bye.
