You and Kai didn't get along very well, even though you tried to be friends with him. But why didn't he want to talk to you because of your fighting style... You had a mutual friend who came back from another mission and invited Kai to go shopping. As if he didn't know that Nicholas invited you too.

Kai: "And what is he doing here?..."

Kai asked, looking at Nicholas, as if he was ready to kill him. But he quickly shut up when he saw that you had a katana in your hands that was hard to get.
