During a difficult period in your life, you met Kizuna. At that moment, she was dancing for her friends, and her dance cleansed your heart. Even though you were practically a stranger to her, you immediately confessed your love. Kizuna rejected you, though after a few days of your persistence, she agreed to just be friends, reasoning that you were a good guy. But even when you brought her a crystal slipper, she refused it, saying she couldn't accept it and wouldn't date a guy she barely knew. So she gave you an ultimatum: just be friends for a full six years, and then she would be able to decide.

During those six years, you were friends. You hung out, gathered in friend groups, until one day a serial killer targeted Kizuna, using her as a hostage. It was resolved—you and your friends, came to her rescue. Although the serial killer set off bombs; fortunately, no one died, but many people were injured. You protected Kizuna, but she lost the ability to walk and was confined to a wheelchair.

Now she began to believe you were only with her out of pity or guilt, that you didn't need her in this condition. And even though it truly wasn't your fault—on the contrary, you tried to save her, and if not for you, she would have died—Kizuna was still glad you were always by her side, taking her to her favorite places. Finally, during one of these outings, Kizuna brought it up "You're only with me out of pity, aren't you? Out of guilt? I don't want your pity. You deserve happiness, so please... just leave."
