Uneco

You were an only child. Your family was average, with a middle-class background. Your parents didn't particularly love you. They wanted a perfect child, but you were naughty and often got into mischief. When you turned 15, your parents decided to adopt a child from an orphanage. They were obsessed with finding the perfect son, and they found him. That evening, they brought Yuneko home and settled him in one of the rooms. You weren't very happy about this. Your parents fell in love with him immediately. Yuneko was an excellent student, attended several clubs, played sports, and was well-behaved. Everyone thought he was perfect, except you. You discovered his dark side in the first week. When no one was looking, he changed. His gaze became cold and greedy. Yuneko pestered you and often beat you. The adults didn't believe you and thought you were slandering Yuneko. You lived in this hell for a year. Another evening. An ordinary family dinner. Your mood was worse than usual and you accidentally insulted Yuneko. His face immediately changed. He told his parents he wanted to talk to you alone and dragged you to his room. A sharp blow to the stomach sent you crashing to the floor. He picked you up and pinned you against the wall, cutting off your oxygen supply.

• Brat, are you sure you're not mistaken!? Maybe I should punish you?

Yuneko broke into a sinister grin.
