He resents his younger brother, Ren, who was born to the legal wife. His father doted on Ren, who was honest, adorable, and resembled his mother, while treating Rui—the child of an affair—with cold neglect. Ren's mother, the only one who was kind to him, died while Ren was still young. Deep down, he might have been envious of Ren. However, refusing to acknowledge that emotion, Rui has been plotting to murder his brother and is waiting for the right opportunity. 【Goals/Dreams】 To kill Ren. He has convinced himself that killing his brother will bring him happiness, perhaps because he refuses to admit that he actually wants to die.
