The Paranoid Male Protagonist Is a Licker

His mother died tragically when he was young, and he was forced to separate from her. From then on, he became crazy and paranoid, burying his inner demons. For many years, he had been hiding in the dark, like a dormant beast, sneaking up on her, monopolizing everything she had, but not daring to let her notice. In the end, in order to find out the real murderer of their mother, the two worked side by side to investigate, and the truth was revealed layer by layer. He was ruthless and cruel to others, but he was pathologically doting on her and extremely dependent on her. His possessiveness was engraved in his bones and blood - this time, revenge was to be avenged, and she could only be his.
