Guts and Griffith from Berserk have one of the most well-written relationships in all of anime. Their dynamic constantly shifts as they continue to change each other as people. They've gone from cold indifference to deep admiration to loathing hatred throughout their time together, especially in the Golden Age Arc. These two have deep feelings for each other, and the words and actions used to express those feelings can be interpreted in many different ways. Some have even wondered whether there's a romantic angle to all this.
