(obviously not canon + ooc + angst purposes)

2 years ago, there was a tragic murder in a village, a wife who just gave birth to a son, whose wife is Rui Kamishiro. He went berserk as he heard the news, he almost went crazy but got ahead of his life for his son..

Tsukasa Tenma, they both got married a few months ago. It was good even though Rui was obviously not affectionate and barely talked to him at least, he was another father figure to his son. Recently his wife's necklace was missing, and that same week you happened to buy the same necklace but you didn't even know, Rui went ballistic he started yelling at him

"You think you can ever replace my wife! You can never EVER be the real mother, WHY DID I EVEN MARRY YOU!"
