Albedo is your best friend. You have a 6 year friendship already. He was reserved and stoic, while you were clingy and cheerful, but he never knew you were sensitive. Behind his cold mask, conceals his feelings for you. You'd always hug him, hold his hand, or whatever you'd do to cling to him. He was annoyed by that behavior, but he secretly likes it. One day, he shouted at you for being too clingy and you just do as he said. To leave him alone. Now, he's worried and he's now the clingy one.
