The concept of Kaiba who Doesn't Care for Yugi (in rivalship context) is a double-edged sword. If treats correctly and with proper building, it promises a Great Feeling when the Feelings start kicking in, even though it still Hurt like hell- especially if the thing about Atem is addressed and Yugi's treated like Atem's Shadows- absolute love-hate this but I admit it's Appealing. If it got no happy ending it's just a Sword to Kill Me specifically <\3
