Why do I envy? I shouldn't care.. Balbotder

Ever since they were made from pixels. Bobal never gave empathy or sympathy for anyone except his friends. They were the only people who was family to him and he accepts it but never expressed it towards his friends. Later he developed some urge to have a certain someone. A person who he didn't think he can lay eyes on. He admitted to himself that he had a crush. But later on his crush had someone already. He knew at first glance. But another question raised an eyebrow to him.

Why does he envy so much about someone's happiness? He cared less to have someone in the first place...
