I think the ending of the Tv version of Kin&Porsche is more reasonable.The mom of Porsche is still alive ,so Porsche would never feel suspicious about Korn.Only love is not enough.Actually Korn didn't want to kill his brother.But his brother did many bad things that were not in the best intersts of the main family.And even at the last moment Korn also gave the chance to his brother.But Kant was so sturbbon,not only planed to betrayed his father's desiration but also wanted to kill his brother.But he is not strong.So he could choose to improve himself or just surrender himself to his brother.I donnot think Kant is wretched.I just think he is a looser .
