Lin Yi encountered a fire when he was 8 years old and forgot everything when he woke up.
He met Si Yin, and the 15-year-old boy smiled at him and took him home.
Si Yin pampered him and gave him all his tenderness.
Lin Yi always followed him and called him "brother" one after another.
Lin Yi had always thought that Si Yin was like this, but he ignored the paranoia and madness flowing in the shadows under his gentle eyes.
Until Lin Yi knew that the fire in his childhood was not an accident at all.
He finally understood at the age of 18 that Si Yin was a complete madman.
